* mei: reset flow control on the last client disconnectionAlexander Usyskin2015-06-141-0/+3
| | | | | | | | | | | The FW resets the flow control for single buffer clients when the last host client disconnects, also the driver has to follow this policy and zero the flow control counter in such case.

| | | | | | | | | | | | | | If devm_gen_pool_create() fails, the previously enabled sram->clk is not disabled on probe() exit. Because reserved block logic relies only on information from device tree, there is no need to get and enable device clock in advance, especially because not provided clock is not considered as an error, so it is safe to place devm_clk_get() at the end of probe().

Detailed description for patchset: 1. Update the extcon core. - Modify the extcon device name on sysfs from device name name to 'extcon[X]' as following because if same extcon device are included in H/W development board, the one of the two device driver might be failed on the probe(). : /sys/class/extcon/[device name] -> /sys/class/extcon/extcon[X] - Use the unique id for external connectors instead of legacy string name. Previously, extcon used the string name to identify the type of external connectors. This way have the many potential issues. So, extcon core define the unique id for each external connectors as following: enum extcon { EXTCON_NONE = 0x0, /* USB external connector */ EXTCON_USB = 0x1, EXTCON_USB_HOST = 0x2, /* Charger external connector */ EXTCON_TA = 0x10, EXTCON_FAST_CHARGER = 0x11, EXTCON_SLOW_CHARGER = 0x12, EXTCON_CHARGE_DOWNSTREAM = 0x13, /* Audio and video external connector */ EXTCON_LINE_IN = 0x20, EXTCON_LINE_OUT = 0x21, EXTCON_MICROPHONE = 0x22, EXTCON_HEADPHONE = 0x23, ... }; - Update tye prototype of extcon_register_notifier() by using the unique id (enum extcon) of external connectors. - Add extcon_get_edev_name() API to get the name of extcon device on extcon client driver because the name is included in 'struct extcon_dev' and 'struct extcon_dev' should be handled in only drivers/extcon directory. So. if extcon client need the name of extcon device, they could use this function. - Unify the jig/dock and MHL-TA cable name on extcon driver. : JIG-{USB-ON|USB-OFF|UART-ON|UART-OFF} -> JIG : Dock-{Smart|Desk|Audio|Card} -> DOCK : MHL-TA -> TA - Use the capital letter for the name of all external connectors. - Remove the optional print_name() function pointer from struct extcon_dev to maintain the consistent name of extcon device. 2. Add the new extcon-axp288.c extcon driver. - The extcon-axp288.c driver support for AXP288 PMIC which has the BC1.2 charger detection capability. So this extcon driver can detect the EXTCON_SLOW_CHARGER, EXTCON_CHARGE_DOWNSTREAM and EXTCON_FAST_CHARGER. 3. Update the extcon-arizona.c driver. - Add support for selective detection mode when headphone detection. - Apply HP clamps for WM8280 4. Clean-up the extcon core and drivers. - Add manufactor information of each extcon device. - Fix checkpatch warning and minor coding style on extcon.c.c - Fix build break if GPIOLIB is not enabled on extcon-usb-gpiio.c. - Set the direction of gpio when calling devm_gpiod_get() on extcon-usb-gpio.c
| * extcon: Remove optional print_name() function pointer of extcon_devChanwoo Choi2015-05-292-11/+0
| | | | | | | | | | | | | | | | | | | | | | This patch removes the optional print_name() function pointer included in 'struct extcon_dev' because the extcon must maintain the consistent name of extcon device on sysfs instead of inconsistent name. After merged patch[1], extcon can maintain the consistent name of extcon device without any hard-coded device name.

When registering the notifier chain for specific external connector with extcon_register_interest(), it used the the string name of external connector directly. There are potential problem because of unclear, non-standard and inconsequent cable name. Namely, it is not appropriate method to identify each external connector. So, this patch modify the prototype of extcon_register_notifier() by using the 'enum extcon' which are the unique id for each external connector instead of unclear string method. - Previously, the extcon consumer driver used the extcon_register_interest() with 'cable_name' to point out the specific external connector. Also. it used the un-needed structure (struct extcon_specific_cable_nb). : int extcon_register_interest(struct extcon_specific_cable_nb *obj, const char *extcon_name, const char *cable_name, struct notifier_block *nb) - Newly, the updated extcon_register_notifier() would definitely support the same feature to detech the changed state of external connector without any specific structure (struct extcon_specific_cable_nb). : int extcon_register_notifier(struct extcon_dev *edev, enum extcon id, struct notifier_block *nb) This patch support the both extcon_register_interest() and new extcon_register_ notifier(). But the extcon_{register|unregister}_interest() will be deprecated because extcon core would support the notifier event for extcon consumer driver with only updated extcon_register_notifier() and 'extcon_specific_cable_nb' will be removed if there are no extcon consumer driver with legacy extcon_{register|unregister}_interest().

The string name have the many potential issues. So, this patch defines the 'extcon' enumeration which includes all supported external connector on EXTCON subsystem. If new external connector is necessary, the unique id of new connector have to be added in 'extcon' enumeration. There are current supported external connector in 'enum extcon' as following: enum extcon { EXTCON_NONE = 0x0, /* USB external connector */ EXTCON_USB = 0x1, EXTCON_USB_HOST = 0x2, /* Charger external connector */ EXTCON_TA = 0x10, EXTCON_FAST_CHARGER = 0x11, EXTCON_SLOW_CHARGER = 0x12, EXTCON_CHARGE_DOWNSTREAM = 0x13, /* Audio and video external connector */ EXTCON_LINE_IN = 0x20, EXTCON_LINE_OUT = 0x21, EXTCON_MICROPHONE = 0x22, EXTCON_HEADPHONE = 0x23, EXTCON_HDMI = 0x30, EXTCON_MHL = 0x31, EXTCON_DVI = 0x32, EXTCON_VGA = 0x33, EXTCON_SPDIF_IN = 0x34, EXTCON_SPDIF_OUT = 0x35, EXTCON_VIDEO_IN = 0x36, EXTCON_VIDEO_OUT = 0x37, /* Miscellaneous external connector */ EXTCON_DOCK = 0x50, EXTCON_JIG = 0x51, EXTCON_MECHANICAL = 0x52, EXTCON_END, }; For example in extcon-arizona.c: To use unique id removes the potential issue about handling the inconsistent name of external connector with string. - Previously, use the string to register the type of arizona jack connector static const char *arizona_cable[] = { "Mechanical", "Microphone", "Headphone", "Line-out", }; - Newly, use the unique id to register the type of arizona jack connector static const enum extcon arizona_cable[] = { EXTCON_MECHANICAL, EXTCON_MICROPHONE, EXTCON_HEADPHONE, EXTCON_LINE_OUT, EXTCON_NONE, }; And this patch modify the prototype of extcon_{get|set}_cable_state_() which uses the 'enum extcon id' instead of 'cable_index'. Because although one more extcon drivers support USB cable, each extcon driver might has the differnt 'cable_index' for USB cable. All extcon drivers can use the unique id number for same external connector with modified extcon_{get|set}_cable_state_(). - Previously, use 'cable_index' on these functions: extcon_get_cable_state_(struct extcon_dev*, int cable_index) extcon_set_cable_state_(struct extcon_dev*, int cable_index, bool state) -Newly, use 'enum extcon id' on these functions: extcon_get_cable_state_(struct extcon_dev*, enum extcon id) extcon_set_cable_state_(struct extcon_dev*, enum extcon id, bool state) Cc: Arnd Bergmann <arnd@arndb.de> Cc: Felipe Balbi <balbi@ti.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Roger Quadros <rogerq@ti.com> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Acked-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com> Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> [arnd: Report the build break about drivers/usb/phy/phy-tahvo.c after using the unique id for external connector insteadf of string] Reported-by: Arnd Bergmann <arnd@arndb.de> [dan.carpenter: Report the build warning of extcon_{set|get}_cable_state_()] Reported-by: Dan Carpenter <dan.carpenter@oracle.com>

The current protocol distributed the primary channels uniformly across all available CPUs. The new protocol is NUMA aware: primary channels are distributed across the available NUMA nodes while the sub-channels within a primary channel are distributed amongst CPUs within the NUMA node assigned to the primary channel.
