* parisc: use long branch in fork_like macroJohn David Anglin2013-05-061-1/+2
| | | | | | | | | | | The "b" branch instruction used in the fork_like macro only can handle 17-bit pc-relative offsets. This fails with an out of range offset with some .config files. Rewrite to use the "be" instruction which can branch to any address in a space. Signed-off-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de>
* parisc: fix NATIVE set up in buildMike Frysinger2013-05-061-3/+1
| | | | | | | | | The ifeq operator does not accept globs, so this little bit of code will never match (unless uname literally prints out "parsic*"). Rewrite to use a pattern matching operator so that NATIVE is set to 1 on parisc. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Helge Deller <deller@gmx.de>

* parisc: fix partly 16/64k PAGE_SIZE bootHelge Deller2013-05-066-25/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the assembler PTE lookup code and the assembler TEMPALIAS code. Furthermore some data alignments for PAGE_SIZE have been limited to 4K (or less) to not waste too much memory with greater page sizes. As a side note, the palo loader can (currently) only handle up to 10 ELF segments which is fixed with tighter aligning as well. My testings indicated that the ldci command in the sba iommu coding needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page size was only set to 4K for my machine (C3000). All this fixes partly the boot, but there are still quite some caching problems left. Examples are e.g. the symbios logic driver which is failing: sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69 sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED. and the tulip network driver which doesn't seem to work correctly either: Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1 link partner capability of 05e1 ..... timed out! Beside those kernel fixes glibc will need fixes too to be able to handle >4K page sizes. Signed-off-by: Helge Deller <deller@gmx.de>
* parisc: Provide default implementation for dma_{alloc, free}_attrsDamian Hobson-Garcia2013-05-061-0/+3
| | | | | | | | | | | | Most architectures that define CONFIG_HAVE_DMA, have implementations for both dma_alloc_attrs() and dma_free_attrs(). All achitectures that do not define CONFIG_HAVE_DMA also have both of these definitions provided by dma-mapping-broken.h. Add default implementations for these functions on parisc.

This controller is accessible through i2c or SPI. - Silicon Laboratories 476x controller, providing access to their FM chipset and their audio codec. - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader. - Nokia's Tahvo power button and watchdog device. This device is very similar to Retu and is thus supported by the same code base. - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by the stmpe driver. - ST-Ericsson AB8540 and AB8505 power management and voltage converter controllers through the existing ab8500 code. Some other drivers got cleaned up or improved. In particular: - The Linaro/STE guys got the ab8500 driver in sync with their internal code through a series of optimizations, fixes and improvements. - The AS3711 and OMAP USB drivers now have DT support. - The arizona clock and interrupt handling code got improved. - The wm5102 register patch and boot mechanism also got improved." * tag 'mfd-3.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next: (104 commits) mfd: si476x: Don't use 0bNNN mfd: vexpress: Handle pending config transactions mfd: ab8500: Export ab8500_gpadc_sw_hw_convert properly mfd: si476x: Fix i2c warning mfd: si476x: Add header files and Kbuild plumbing mfd: si476x: Add chip properties handling code mfd: si476x: Add the bulk of the core driver mfd: si476x: Add commands abstraction layer mfd: rtsx: Support RTS5249 mfd: retu: Add Tahvo support mfd: ucb1400: Pass ucb1400-gpio data through ac97 bus mfd: wm8994: Add some OF properties mfd: wm8994: Add device ID data to WM8994 OF device IDs input: Export matrix_keypad_parse_of_params() mfd: tps65090: Add compatible string for charger subnode mfd: db8500-prcmu: Support platform dependant device selection mfd: syscon: Fix warnings when printing resource_size_t of: Add stub of_get_parent for non-OF builds mfd: omap-usb-tll: Convert to devm_ioremap_resource() mfd: omap-usb-host: Convert to devm_ioremap_resource() ...

| * mfd: wm8994: Don't use system PM operationsMark Brown2013-04-091-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | For realistic systems the power management is controlled entirely via runtime PM - if the device is not runtime suspended then the suspend will abort without doing anything as functionality such as accessory detection or audio bypass will require the device to be enabled while if the device is runtime suspended it is already in the lowest power state. This means that system suspend is redundant and can be removed which avoids issues with attempting to double disable the regulators.

| | | | | | | | | | | | | | | | | | | | | | AB8500 asserts LATCH bits for masked out interrupts. This patch explicitly masks those out using the cached mask value to prevent handle_nested_irq() being called for masked IRQ on the same register as unmasked ones.

| | | | | | | | | | | | | | | | | | | | | | | | Twelve Kconfig symbols, all related to WM8350, WM8351, and WM8352, are unused. Commit 19d57ed5a308472a02e773f33c03ad4cb2ec6a9 ("mfd: Remove custom wm8350 cache implementation") removed all their (actual) users. Remove these symbols too.

| | | | | | | | | | | | | | | | | | | | | | | | This patch changes the irq state from high to the now default low. Because the default PMIC irq state of DA9055 got changed from high to low. This change should not affect any of the existing users since all of them use active low state. This patch has been tested on smdkv6410.

| | | | | | | | | | | | | | | | | | | | | | | | This is because we want to get rid of platform_data usage from probe(). The only information we need is PORT_MODE, and this can be supplied to us by the user (i.e. omap-usb-host.c). We also move channel clock management from runtime PM handlers into omap_tll_enable/disable(). Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
