The pinctrl pull up/down register on exynos4210 is 2-bit wide for each pin and it accepts only values of 0, 1 and 3. The pins sd4-bus-width8 were configured with value of 4. The driver does not validate the value so this overflow effectively set a bit 1 in adjacent pins thus configuring them to pull down. The author's intention was probably to set drive strength of 4x. All other bus-widths pins are configured with pull up and drive strength of 4x. Fix this one with same pattern.

commit f7061ffb44116490f282f130a220ca2d10849248 upstream.

The pinctrl pull up/down register on exynos4210 is 2-bit wide for each
pin and it accepts only values of 0, 1 and 3.  The pins sd4-bus-width8
were configured with value of 4.  The driver does not validate the value
so this overflow effectively set a bit 1 in adjacent pins thus
configuring them to pull down.

The author's intention was probably to set drive strength of 4x.  All

ARM: 8618/1: decompressor: reset ttbcr fields to use TTBR0 on ARMv7 2016-11-20T01:17:36+00:00 Srinivas Ramana sramana@codeaurora.org 2016-09-30T14:03:31+00:00 5f72dd0b5bcdfa8a84f433f7ff9e5cef53f22295 commit 117e5e9c4cfcb7628f08de074fbfefec1bb678b7 upstream. If the bootloader uses the long descriptor format and jumps to kernel decompressor code, TTBCR may not be in a right state. Before enabling the MMU, it is required to clear the TTBCR.PD0 field to use TTBR0 for translation table walks. The commit dbece45894d3a ("ARM: 7501/1: decompressor: reset ttbcr for VMSA ARMv7 cores") does the reset of TTBCR.N, but doesn't consider all the bits for the size of TTBCR.N. Clear TTBCR.PD0 field and reset all the three bits of TTBCR.N to indicate the use of TTBR0 and the correct base address width.
