* ARM: at91: add Kconfig options for common clk supportBoris BREZILLON2013-12-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following Kconfig options to prepare the transition to common clk framework: - AT91_USE_OLD_CLK: this option is selected by every SoC which does not support new at91 clks based on common clk framework (SoC which does not define the clock tree in its device tree). This options is also selected when the user choose non dt boards support (new at91 clks can only be registered from a device tree definition). - COMMON_CLK_AT91: this option cannot be selected directly. Instead it is enabled if these 3 conditions are met: * at least one of the selected SoCs have a PMC (Power Management Controller) Unit * device tree support is enabled * the old at91 clk implementation is disabled (every selected SoC define its clks in its device tree and non dt boards support is disabled) - OLD_CLK_AT91: this option cannot be selected directly. Instead it is enabled if these 2 conditions are met: * at least one of the selected SoCs have a PMC (Power Management Controller) Unit * at least one of the selected SoCs does not define its clks in its device tree or non dt-boards support is enabled This patch selects AT91_USE_OLD_CLK in all currently supported SoCs. These selects will be removed after clk definitions are properly added in each soc's device tree. It also selects AT91_USE_OLD_CLK in all non-dt boards support. AT91_PMC_UNIT references are replaced by OLD_CLK_AT91, because PMC Unit is enabled for both old and common clk implementations, and old clk implementation should not be compiled if COMMON_CLK is enabled. To avoid future link errors, a new stub is created for at91_dt_clock_init function if OLD_CLK_AT91 is disabled. A new check is added in dt init functions (setup.c) to prepare for SoCs supporting new clk implementation. These SoCs won't setup the register_clocks callback (clk registration is done using of_clk_init).

* ARM: at91: fix hanged boot due to early rtt-interruptJohan Hovold2013-11-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure the RTT-interrupts are masked at boot by adding a new helper function to be used at SOC-init. This fixes hanged boot on all AT91 SOCs with an RTT, for example, if an RTT-alarm goes off after a non-clean shutdown (e.g. when using RTC wakeup). The RTC and RTT-peripherals are powered by backup power (VDDBU) (on all AT91 SOCs but RM9200) and are not reset on wake-up, user, watchdog or software reset. This means that their interrupts may be enabled during early boot if, for example, they where not disabled during a previous shutdown (e.g. due to a buggy driver or a non-clean shutdown such as a user reset). Furthermore, an RTC or RTT-alarm may also be active. The RTC and RTT-interrupts use the shared system-interrupt line, which is also used by the PIT, and if an interrupt occurs before a handler (e.g. RTC-driver) has been installed this leads to the system interrupt being disabled and prevents the system from booting. Note that when boot hangs due to an early RTC or RTT-interrupt, the only way to get the system to start again is to remove the backup power (e.g. battery) or to disable the interrupt manually from the bootloader. In particular, a user reset is not sufficient. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: stable@vger.kernel.org # 3.11.x

* ARM: at91: fix at91_extern_irq usage for non-dt boardsJean-Christophe PLAGNIOL-VILLARD2013-06-211-1/+1
| | | | | | | | | | | | | | | | | Since 4b68520dc0ec96153bc0d87bca5ffba508edfcf ARM: at91: add AIC5 support we allocate the at91_extern_irq. This patch makes it static and stores the non-dt extern irq in the soc structure. It is then possible to use a at91_get_extern_irq() function to get the value for outside of the irq driver. It is useful for passing its value to at91_aic_init().

* ARM: delete struct sys_timerStephen Warren2012-12-241-4/+3
| | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

| | | | | | | | | | | | | The number of lines of AIC5 has increased from 32 to 128. Due to this increase, a source select register has been introduced for the interrupt line selection. Moreover, register mapping has been changed. For that reasons, we need some dedicated callbacks for AIC5. Power management is also concerned by these changes. On suspend, we can't get the whole interrupt mask register as before, we have to read this register 128 times. To reduce this overhead, a snapshot of the whole IMR is maintained.

* ARM: at91: AIC and GPIO IRQ device tree initializationNicolas Ferre2012-03-011-0/+6
| | | | | | | | | | | | | | | | Both AIC and GPIO controllers are now using the standard of_irq_init() function to initialize IRQs in case of DT use. The DT specific initialization functions are now separated from the non-DT case and are now using "linear" irq domains. The .map() irqdomain operation is responsible for positioning the IRQ handlers. In AIC case, the Linux IRQ number is directly programmed in the hardware to avoid an additional reverse mapping operation. The AIC position its irq domain as the "default" irq domain. For DT case, the priority is not yet filled in the SMR. It will be the subject of another patch. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>

* AT91: reset: extend alternate reset procedure to several chipsNicolas Ferre2010-10-261-0/+3
| | | | | | | | | Several at91sam9 chips need the alternate reset procedure to be sure to halt SDRAM smoothly before resetting the chip. This is an extension of previous patch "Fix AT91SAM9G20 reset" to all chips affected. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>

* [ARM] 5572/1: at91: Support for at91sam9g45 series: core chip & board supportNicolas Ferre2009-06-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Here are the at91 specific files dedicated to the at91sam9g45 series. They mimic the traditional at91 way of managing chips & boards. The first board that embeds at91sam9g45 chip is the AT91SAM9G45-EKES. In the future, the main board for this 9g45 series will be the AT91SAM9M10G45-EK (I choose this last name for the board file). Simple drivers are enabled in _devices and board- files. Newer peripheral support will be added in future patches. Incuded peripherals support (for now): - USART - SPI - Ethernet - NAND flash - LCD - gpio/joystick/buttons - leds and pwm Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4739/1: at91sam9263: make gpio bank C and D irqs workDavid Brownell2008-02-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | On the at91sam9263, IRQs for GPIO banks C and D don't currently work. This is because banks C, D, and E share one clock and toplevel IRQ, but the AT91 code setting up and handling GPIO IRQs expects no sharing. This patch: - Fixes GPIO IRQ setup and handling to cope with GPIO banks that are shared like on sam9263 chips, by setting up a list of those banks and making the IRQ dispatching logic scan that list. - Precomputes the address of each bank's registers, saving it with other per-bank data so that it no longer needs to be constantly recomputed during IRQs and other GPIO operations. That shrinks hot-path code, while helping the GPIO bank irq updates. - Fixes a minor bug where IRQ_TYPE_NONE was wrongly rejected (it just means "use the default", which is "both edges" here).
