This avoids deadlocks/workarounds when the mux itself needs i2c commands for muxing. And as a side-effect, other workarounds in the media layer could be eliminated. Also, Peter stepped up as the i2c mux maintainer and will keep an eye on these changes. - major updates to the octeon driver - add a helper to the core to generate the address+rw_bit octal and make drivers use it - quite a bunch of driver updates * 'i2c/for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (84 commits) i2c: rcar: add DMA support i2c: st: Implement bus clear i2c: only check scl functions when using generic recovery i2c: algo-bit: declare i2c_bit_quirk_no_clk_stretch as static i2c: tegra: disable clock before returning error [media] rtl2832: regmap is aware of lockdep, drop local locking hack [media] rtl2832_sdr: get rid of empty regmap wrappers [media] rtl2832: change the i2c gate to be mux-locked [media] si2168: change the i2c gate to be mux-locked iio: imu: inv_mpu6050: change the i2c gate to be mux-locked i2c: mux: document i2c muxes and elaborate on parent-/mux-locked muxes i2c: mux: relax locking of the top i2c adapter during mux-locked muxing i2c: muxes always lock the parent adapter i2c: allow adapter drivers to override the adapter locking i2c: uniphier: add "\n" at the end of error log i2c: mv64xxx: remove CONFIG_HAVE_CLK conditionals i2c: mv64xxx: use clk_{prepare_enable,disable_unprepare} i2c: mv64xxx: handle probe deferral for the clock i2c: mv64xxx: enable the driver on ARCH_MVEBU i2c: octeon: Add workaround for broken irqs on CN3860 ...

| * [media] rtl2832: change the i2c gate to be mux-lockedPeter Rosin2016-05-045-181/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The root i2c adapter lock is then no longer held by the i2c mux during accesses behind the i2c gate, and such accesses need to take that lock just like any other ordinary i2c accesses do. So, declare the i2c gate mux-locked, and zap the regmap overrides that makes the i2c accesses unlocked and use plain old regmap accesses. This also removes the need for the regmap wrappers used by rtl2832_sdr, so deconvolute the code further and provide the regmap handle directly instead of the wrapper functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building the exynos-gsc driver with CONFIG_OF disabled, we get a warning about an out-of-bounds access: drivers/media/platform/exynos-gsc/gsc-core.c: In function 'gsc_probe': drivers/media/platform/exynos-gsc/gsc-core.c:1078:34: error: array subscript is above array bounds [-Werror=array-bounds] This is harmless because the driver will never be used without CONFIG_OF, but it's better to avoid the warning anyway. Checking the return value of of_alias_get_id() for an error condition is probably a good idea anyway, and it makes sure the compiler can verify that we don't get into that situation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tvp5150_write() function calls i2c_smbus_write_byte_data() that can fail but does not propagate the error to the caller. Instead it just prints a debug, so callers can't know if the operation failed. So change the function to return the error code to the caller so it knows that the write failed and also print an error instead of just printing a debug information. While being there remove the inline keyword from tvp5150_write() to make it consistent with tvp5150_read() and also because it's called in a lot of places, so making inline is in fact counter productive since it makes the kernel image size to be much bigger (~16 KiB).

It seems to be common knowledge in many projects that changing the USB parameters seems to help. OpenELEC has included this patch for a few years, for example. Nobody bothered to report the issue upstream though, it seems. https://github.com/OpenELEC/OpenELEC.tv/issues/1957 http://www.vdr-portal.de/board60-linux/board14-betriebssystem/board96-yavdr/p1033458-darstellungsproblem-bei-2-tt-3600-usb/#post1033458 (in German) Signed-off-by: Olli Salonen <olli.salonen@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

This shouldn't happen, but I feel happier if the code guards against this. - If g_selection exists, then ignore ENOTTY and ENOIOCTLCMD error codes from cropcap. Just assume square pixelaspect ratio in that case. This situation can happen if the bridge driver's cropcap op calls the corresponding subdev's op. So the cropcap ioctl is set, but it might return ENOIOCTLCMD anyway. In the past this would just return an error which is wrong. - Call cropcap first and let g_selection overwrite the bounds and defrect. This safeguards against subdev cropcap implementations that set those rectangles as well. What g_selection returns has priority over what such cropcap implementations return.
