And named_timeout as a timeout setting should be not less than zero.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit e95fd518 ] Super-IO accesses may fail on a system with no or unmapped LPC bus. Also, other drivers may attempt to access the LPC bus at the same time, resulting in undefined behavior. Use request_muxed_region() to ensure that IO access on the requested address space is supported, and to ensure that access by multiple drivers is synchronized.

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.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 7f0d0786 ] Commit 747834ab ("ARM: OMAP2+: hwmod: revise hardreset behavior") made the call to _enable() conditional based on no oh->rst_lines_cnt. This caused the return value to be potentially uninitialized. Curiously we see no compiler warnings for this, probably as this gets inlined. We call _setup_reset() from _setup() and only _setup_postsetup() if the return value is zero. Currently the return value can be uninitialized for cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit ca70ea43 ] MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to perform low-level platform initialization. This results in a try to install HYP stubs for the second time for each CPU and results in false HYP/SVC mode mismatch detection. The HYP stubs are already installed at the beginning of the kernel initialization on the boot CPU (head.S) or in the secondary_startup() for other CPUs. To fix this issue MCPM code should use a cpu_resume() routine without HYP stubs installation. This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid XU3/XU4/HC1 boards.
