media: v4l2: i2c: ov7670: Fix PLL bypass register values

2019-05-08T05:20:53Z

commit 61da76beef1e4f0b6ba7be4f8d0cf0dac7ce1f55 upstream. The following commits: commit f6dd927f34d6 ("[media] media: ov7670: calculate framerate properly for ov7675") commit 04ee6d92047e ("[media] media: ov7670: add possibility to bypass pll for ov7675") introduced the ability to bypass PLL multiplier and use input clock (xvclk) as pixel clock output frequency for ov7675 sensor. PLL is bypassed using register DBLV[7:6], according to ov7670 and ov7675 sensor manuals. Macros used to set DBLV register seem wrong in the driver, as their values do not match what reported in the datasheet. Fix by changing DBLV_* macros to use bits [7:6] and set bits [3:0] to default 0x0a reserved value (according to datasheets). While at there, remove a write to DBLV register in "ov7675_set_framerate()" that over-writes the previous one to the same register that takes "info->pll_bypass" flag into account instead of setting PLL multiplier to 4x unconditionally. And, while at there, since "info->pll_bypass" is only used in set/get_framerate() functions used by ov7675 only, it is not necessary to check for the device id at probe time to make sure that when using ov7670 "info->pll_bypass" is set to false.

clk: x86: Add system specific quirk to mark clocks as critical

2019-05-08T05:20:53Z

commit 7c2e07130090ae001a97a6b65597830d6815e93e upstream. Since commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL"), the pmc_plt_clocks of the Bay Trail SoC are unconditionally gated off. Unfortunately this will break systems where these clocks are used for external purposes beyond the kernel's knowledge. Fix it by implementing a system specific quirk to mark the necessary pmc_plt_clks as critical.

Input: stmfts - acknowledge that setting brightness is a blocking call

2019-05-08T05:20:53Z

commit 937c4e552fd1174784045684740edfcea536159d upstream. We need to turn regulators on and off when switching brightness, and that may block, therefore we have to set stmfts_brightness_set() as LED's brightness_set_blocking() method.

Input: snvs_pwrkey - initialize necessary driver data before enabling IRQ

2019-05-08T05:20:52Z

commit bf2a7ca39fd3ab47ef71c621a7ee69d1813b1f97 upstream. SNVS IRQ is requested before necessary driver data initialized, if there is a pending IRQ during driver probe phase, kernel NULL pointer panic will occur in IRQ handler. To avoid such scenario, just initialize necessary driver data before enabling IRQ. This patch is inspired by NXP's internal kernel tree.

staging: iio: adt7316: fix the dac write calculation

2019-05-08T05:20:52Z

commit 78accaea117c1ae878774974fab91ac4a0b0e2b0 upstream. The lsb calculation is not masking the correct bits from the user input. Subtract 1 from (1 << offset) to correctly set up the mask to be applied to user input. The lsb register stores its value starting at the bit 7 position. adt7316_store_DAC() currently assumes the value is at the other end of the register. Shift the lsb value before storing it in a new variable lsb_reg, and write this variable to the lsb register.
