* flash: complete CONFIG_SYS_NO_FLASH move with renamingMasahiro Yamada2017-02-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is not completed. Finish this work by the tool. During this move, let's rename it to CONFIG_MTD_NOR_FLASH. Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH" than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will make the code more readable. Besides, negative meaning symbols do not fit in obj-$(CONFIG_...) style Makefiles. This commit was created as follows: [1] Edit "default n" to "default y" in the config entry in common/Kconfig. [2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH" [3] Rename the instances in defconfigs by the following: find . -path './configs/*_defconfig' | xargs sed -i \ -e '/CONFIG_SYS_NO_FLASH=y/d' \ -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/' [4] Change the conditionals by the following: find . -name '*.[ch]' | xargs sed -i \ -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \ -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \ -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \ -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/' [5] Modify the following manually - Rename the rest of instances - Remove the description from README - Create the new Kconfig entry in drivers/mtd/Kconfig - Remove the old Kconfig entry from common/Kconfig - Remove the garbage comments from include/configs/*.h Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* imx: mx6: Fix procedure to switch the parent of LDB_DI_CLKAkshay Bhat2016-04-19-0/+151
| | | | | | | | | | | | | | | | | | | | | Due to incorrect placement of the clock gate cell in the ldb_di[x]_clk tree, the glitchy parent mux of ldb_di[x]_clk can cause a glitch to enter the ldb_di_ipu_div divider. If the divider gets locked up, no ldb_di[x]_clk is generated, and the LVDS display will hang when the ipu_di_clk is sourced from ldb_di_clk. To fix the problem, both the new and current parent of the ldb_di_clk should be disabled before the switch. This patch ensures that correct steps are followed when ldb_di_clk parent is switched in the beginning of boot. This patch was ported from the 3.10.17 NXP kernel http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/commit/?h=imx_3.10.17_1.0.1_ga&id=eecbe9a52587cf9eec30132fb9b8a6761f3a1e6d NXP errata number: ERR009219, EB821 Signed-off-by: Akshay Bhat <akshay.bhat@timesys.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@nxp.com>
