* imx: iomux-v3: Include PKE and PUE to pad control pull definitionsBenoît Thébaudeau2013-04-28-99/+73
| | | | | | | | | | | | | | | | | PUE requires PKE to mean something, as do pull values with PUE, so do not compell users to explicitly use PKE and PUE everywhere. This is also what is done on Linux and what has already been done for i.MX51. By the way, remove some unused pad control definitions. There is no change of behavior. Note that SPI_PAD_CTRL was defined by several boards with a pull value, but without PKE or PUE, which means that no pull was actually enabled in the pad. This might be a bug in those boards, but this patch does not change the behavior, so it just removes the meaningless pull value from those definitions.

* imx: Homogenize and fix fuse register definitionsBenoît Thébaudeau2013-04-28-1/+4
| | | | | | | | | | | | | | | | | | IIM: - Homogenize prg_p naming (the reference manuals are not always self-consistent for that). - Add missing SCSx and bank registers. - Fix the number of banks on i.MX53. OCOTP: - Rename iim to ocotp in order to avoid confusion. - Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the reference manual. - Merge the existing spinoff gp1 fuse definition on i.MX6. - Fix the number of banks on i.MX6.

| | | | | | | | | | | | CKO1 drives sgtl5000 codec clock on nitrogen boards and wandboard. Doing this setup in the bootloader will allow us to remove a lot of code in arch/arm/mach-imx/mach-imx6q.c from the mainline kernel. Also, according to Eric Nelson: "enabling the clock <in the bootloader> will remove squeal after an ungraceful reboot (watchdog) if hooked up to speakers."

| | | | | | | | | | | | | | Commit 3ebd1cbc introduced compiler-generated __bss_start and __bss_end__ and commit c23561e7 rewrote all __bss_end__ as __bss_end.

| * nand: Extend nand_(read|write)_skip_bad with *actual and limit parametersTom Rini2013-04-10-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We make these two functions take a size_t pointer to how much space was used on NAND to read or write the buffer (when reads/writes happen) so that bad blocks can be accounted for. We also make them take an loff_t limit on how much data can be read or written. This means that we can now catch the case of when writing to a partition would exceed the partition size due to bad blocks. To do this we also need to make check_skip_len count not just complete blocks used but partial ones as well. All callers of nand_(read|write)_skip_bad are adjusted to call these with the most sensible limits available. The changes were started by Pantelis and finished by Tom.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPLL is selected as the source clk of pwm by default Test with command "sf probe 1:0; time sf read 40008000 0 1000". Try with different numbers of bytes and see that sane values are obtained Build and boot U-boot with this patch, backlight works properly.

| * | | Exynos5: clock: Fix a typo bug in exynos clock initAkshay Saraswat2013-03-29-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We intended to clear the bits of CLK_SRC_TOP2 register, instead we were writing on the reserved bits of src_core1 register. Since the default value of clk_src_top2 register were itself zero, this typo was not creating any big issue. But it is better to fix this error for better readability of the code.
