| * Keyboard: omap-keypad: use matrix_keypad.hJanusz Krzysztofik2010-12-2215-387/+437
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most keypad drivers make use of the <linux/input/matrix_keypad.h> defined macros, structures and inline functions. Convert omap-keypad driver to use those as well, as suggested by a compile time warning, hardcoded into the OMAP <palt/keypad.h>. Created against linux-2.6.37-rc5. Tested on Amstrad Delta. Compile tested with omap1_defconfig and omap2plus_defconfig shrinked to board-h4.

| * omap: rx51: Remove tvout code that plays with gpio 40Jarkko Nikula2010-12-221-20/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 60d24ee "Added video data to support tvout on rx51" added code that tries to assign gpio 40 as OMAP DSS reset_gpio for tvout. This is wrong since this gpio has nothing to do with OMAP DSS but it is used to control one switch that selects is the audio jack connected to tvout or audio circuitry. This switch is already supported by the RX51 ASoC driver so there is no need to control it elsewhere. Switch is contolled with ALSA control 'Jack Function' and tvout can be selected with following example: amixer -D hw:0 set 'Jack Function' 'TV-OUT' Signed-off-by: Jarkko Nikula <jhnikula@gmail.com> Cc: Srikar <ext-srikar.1.bhavanarayana@nokia.com> Acked-by: Tomi Valkeinen <tomi.valkeinen@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| * OMAP4: Pandaboard: Fix MMC card detect gpio lineRaghuveer Murthy2010-12-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit bf56f0a6668cd (2.6.37-rc1), from Nishanth Menon attempted to fix card detection for PandaBoard, unfortunately, the fix missed to initialize .gpio_cd member of omap2_hsmmc_info. This results in a default value of '0', which is a valid GPIO line. On PandaBoard, the side effect of this is that GPIO line 0 controls the powering TFP410 DVI chip, and without the fix DVI chip is inadvertently powered.

The reset behavior is implementation specific as per ARMv7 TRM and hence $L2 needs to be invalidated before it's use. Since the AUXCTRL register is also reconfigured, disable L2 cache before invalidating it and re-enables it afterwards. This is as per Cortex-A8 ARM documentation. Currently this is identified as being needed on OMAP3630 as the disable/enable is done from "public side" while, on OMAP3430, this is done in the "secure side".

This impacts modules with embedded memories on OMAP3630 Workaround is to disable RTA on boot and coming out of core off. For disabling RTA coming out of off mode, we do this by overriding the restore pointer for 3630 as the first point of entry before caches are touched and is common for GP and HS devices. To disable earlier than this could be possible by modifying the PPA for HS devices, but not for GP devices.

IMPORTANT: *) This is not a complete workaround implementation as recommended by the silicon erratum. This is a support logic for detecting lockups and attempting to recover where possible and is known to provide stability in multiple platforms. *) This code is mostly important for inactive and retention. The ROM code waits for the maximum DLL lock time when resuming from off mode. So for off mode this code isn't really needed. *) counters are introduced here for eventual export to userspace once the cleanups are completed.

Today both are device initcalls and it works just because of the order of compilation. Making this postcore_initcall is ideal because the omap device layer init happens as a core_initcall and typically rest of the driver/device inits are arch_initcall or something lower.

SH-Mobile ARM platforms using multiple interrupt priority levels need this patch to fix a potential dead lock that may occur if multiple interrupts with different levels are pending simultaneously. The default INTC configuration is to use the same priority level for all interrupts, so this issue does not trigger by default. It is however common for board code to override the interrupt priority for certain interrupt sources depending on the application. Without this fix such boards may lock up. In detail, this patch updates the INTC code in entry-macro.S to make sure that the INTLVLA register gets set as expected. To trigger this bug modify the board specific code to adjust the interrupt priority level for the ethernet chip. After changing the priority level simply use flood ping to drown the board with interrupts. This patch applies to INTCA-based processors such as sh7372, sh7377 and sh7372. GIC-based processors are not affected. Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

Reused errata handling patch from: Peter Ujfalusi <peter.ujfalusi@nokia.com> https://patchwork.kernel.org/patch/231191/ Changes to above patch: 1. Changes are done for converting all the existing errata work arounds to use this feature. 2. Detailed description for each errata is added. 3. Fixed bug in SET_DMA_ERRATA macro 4.
