|/ | | | | | | | | | | | | | | As a first step towards migrating davinci platforms to use common clock framework, replace all instances of clk_enable() with clk_prepare_enable() and clk_disable() with clk_disable_unprepare(). Until the platform is switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just adds a might_sleep() call and would work without any issues. This will make it easy later to switch to common clk based implementation of clk driver from DaVinci specific driver.

* ASoC/ARM: Davinci: McASP: split asp header into platform and audio specificHebbar, Gururaja2012-08-271-0/+1
| | | | | | | | | | | | | | | | | | Davinci McASP header & driver are shared by few OMAP platforms (like TI81xx, AM335x). Splitting asp header into Davinci platform specific header and Audio specific header helps to share them across platforms. Audio specific defines is moved to to common <linux/platform_data/davinci_asp.h> so that the header can be accessed by all related platforms. While here, correct the header usage (remove multiple header re-definitions and unused headers) and remove platform names from structures comments and enum. Also some some coding style errors.

* ARM: davinci: Explicitly set channel controllers' default queuesIdo Yariv2011-09-171-0/+3
| | | | | | | | | | | | | | | | | | Davinci platforms may define a default queue for each channel controller. If one is not defined, the default queue is set to EVENTQ_1. However, there's no way to distinguish between an unset default queue to one that is set to EVENTQ_0, as EVENTQ_0 = 0. Explicitly specify the default queue for all channel controllers on all Davinci platforms to EVENTQ_1, and don't overwrite it in the EDMA probe function. One exception is the DA850 board, for which EVENTQ_1 is not a valid option for its second channel controller. Use EVENTQ_0 instead for that channel controller.

* davinci: da850: add support for SATA interfaceSekhar Nori2011-07-081-0/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for SATA controller on the DA850/OMAP-L138/AM18x devices. The patch adds the necessary clocks, platform resources and a routine to initialize the SATA controller. The PHY configuration in this patch is courtesy the work done by Zegeye Alemu, Swaminathan and Mansoor Ahamed from TI. While testing this patch, enable port multiplier support iff you are actually using one. The reasons of this behaviour are discussed here: http://patchwork.ozlabs.org/patch/78163/ ChangeLog: v3: Removed fields which were being initialized to zero in PHY configuration. Moved SATA base address definition to the top of the file to make it inline with what is done for the rest of the modules. v2: Addressed comments from Sergei. Removed unnecessary braces and removed unnecessary else after goto. Signed-off-by: Sekhar Nori <nsekhar@ti.com>

* davinci: edma: provide ability to detect insufficient CC info dataSekhar Nori2010-08-051-11/+18
| | | | | | | | | | | | | | | | This patch modifies the EDMA driver to expect the channel controller (CC) infomation passed on by the platform as a fixed size (EDMA_MAX_CC) array of pointers to structures. Doing so helps catch errors of the sort where the resource structure has information for more channel controllers than the number channel controller info structures defined.

* Davinci: watchdog reset separation across socsCyril Chemparathy2010-05-071-2/+2
| | | | | | | | | | | | | | | | | The earlier watchdog reset mechanism had a couple of limitations. First, it embedded a reference to "davinci_wdt_device" inside common code. This forced all derived platforms (da8xx and tnetv107x) to define such a device. This also would have caused problems in including multiple socs in a single build due to symbol redefinition. With this patch, davinci_watchdog_reset() now takes the platform device as an argument. The davinci_soc_info struct has been extended to include a reset function and a watchdog platform_device. arch_reset() then uses these elements to reset the system in a SoC specific fashion.

* davinci: da8xx: Add base DA830/OMAP-L137 SoC supportMark A. Greer2009-08-261-0/+287
The da830/omap l137 is a new SoC from TI that is similar to the davinci line. Since its so similar to davinci, put the support for the da830 in the same directory as the davinci code. There are differences, however. Some of those differences prevent support for davinci and da830 platforms to work in the same kernel binary. Those differences are: 1) Different physical address for RAM. This is relevant to Makefile.boot addresses and PHYS_OFFSET. The Makefile.boot issue isn't truly a kernel issue but it means u-boot won't work with a uImage including both architectures. The PHYS_OFFSET issue is addressed by the "Allow for runtime-determined PHYS_OFFSET" patch by Lennert Buytenhek but it hasn't been accepted yet. 2) Different uart addresses. This is only an issue for the 'addruart' assembly macro when CONFIG_DEBUG_LL is enabled. Since the code in that macro is called so early (e.g., by _error_p in kernel/head.S when the processor lookup fails), we can't determine what platform the kernel is running on at runtime to use the correct uart address. These areas have compile errors intentionally inserted to indicate to the builder they're doing something wrong. A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added to distinguish between a true davinci architecture and the da830 architecture. Note that the da830 currently has an issue with writeback data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be enabled when building a da830 kernel. Additional generalizations for future SoCs in the da8xx family done by Sudhakar Rajashekhara and Sekhar Nori.
