BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit d3f48ec0 ] lm3630a_bank_a_update_status() and lm3630a_bank_b_update_status() both return the brightness value if the brightness was successfully updated. Writing to these attributes via sysfs would cause a 'Bad address' error to be returned. These functions should return 0 on success, so let's change it to correct that error.

We aren't supposed to use it but we're instead supposed to use the value that gets written to it when we call videobuf_dqbuf(). The videobuf_dqbuf() first memsets it to zero and then re-initializes it inside the videobuf_status() function. It's this final value which we want. Hans Verkuil pointed out that we need to check the return from videobuf_dqbuf(). I ended up doing a little cleanup related to that as well.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 8f4426aa ] The QP transition optional parameters for the various transition for XRC QPs are identical to those for RC QPs. Many of the XRC QP transition optional parameter bits are missing from the QP optional mask table. These omissions caused failures when doing XRC QP state transitions. For example, when trying to change the response timer of an XRC receive QP via the RTS2RTS transition, the new timer value was ignored because MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask for XRC qps for the RTS2RTS transition. Fix this by adding the missing XRC optional parameters for all QP transitions to the opt_mask table.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 648865a7 ] In 2D transfers (for the AXI DMAC), the number of frames (numf) represents Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful for video transfers where screen resolutions ( X * Y ) are typically aligned for X, but not for Y. There is no requirement for Y_LENGTH to be aligned to the bus-width (or anything), and this is also true for AXI DMAC. Checking the Y_LENGTH for alignment causes false errors when initiating DMA transfers. This change fixes this by checking only that the Y_LENGTH is non-zero.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 509c5836 ] The original driver by default defines num_chipselects as -1. This actually allicates an array of 65535 entries in of_spi_register_master. There is a side-effect for buggy device trees that (contrary to dt-binding documentation) have no cs-gpio defined. This mode was never supported by the driver due to limitations of native cs and additional code complexity and is explicitly not stated to be implemented. To keep backwards compatibility with such buggy DTs we limit the number of chip_selects to 1, as for all practical purposes it is only ever realistic to use a single chip select in native cs mode without negative side-effects.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 1a89ac5b ] Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked mode when transfer length is not a multiple of requested bits per word. unpacked mode transfers fails when the transfer includes partial bytes in the last word. Total words to be written/read to/from FIFO is computed based on transfer length and bits per word. Unpacked mode includes 0 padding bytes for partial words to align with bits per word and these extra bytes are also accounted for calculating bytes left to transfer in the current driver. This causes extra bytes access of tx/rx buffers along with buffer index position crossing actual length where remain_len becomes negative and due to unsigned type, negative value is a 32 bit representation of signed value and transferred bytes never meets the actual transfer length resulting in transfer timeout and a hang. This patch fixes this with proper computation of the actual bytes to fill in FIFO during transmit and the actual bytes to read from FIFO during receive ignoring 0 padded bytes. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 0e633f97 ] clang warns about a possible variable use that gcc never complained about: drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here [-Werror,-Wuninitialized] dm365_vpss_set_pg_frame_size(frame_size); ^~~~~~~~~~ drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here struct vpss_pg_frame_size frame_size; ^ 1 error generated. There is no initialization for this variable at all, and there has never been one in the mainline kernel, so we really should not put that stack data into an mmio register. On the other hand, I suspect that gcc checks the condition more closely and notices that the global isif_cfg.bayer.config_params.test_pat_gen flag is initialized to zero and never written to from any code path, so anything depending on it can be eliminated. To shut up the clang warning, just remove the dead code manually, it has probably never been used because any attempt to do so would have resulted in undefined behavior.

This caused the return value to be potentially uninitialized. Curiously we see no compiler warnings for this, probably as this gets inlined.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit e7e7e0d7 ] If the clock tree is not fully populated when the timer-sun5i init code is called, attempts to get the clock rate for the timer would fail and return 0. Make the init code for both clock events and clocksource check the returned clock rate and fail gracefully if the result is 0, instead of causing a divide by 0 exception later on.
