[ Upstream commit e0a7683d ] The Credit Based Shaper heavily depends on link speed to calculate the scheduling credits, we can't properly calculate the credits if the device has failed to report the link speed. In that case we can't dequeue packets assuming a wrong port rate that will result into an inconsistent credit distribution. This patch makes sure we fail to dequeue case: 1) __ethtool_get_link_ksettings() reports error or 2) the ethernet driver failed to set the ksettings' speed value (setting link speed to SPEED_UNKNOWN). Additionally we properly re calculate the port rate whenever the link speed is changed. Fixes: 3d0bd028 ("net/sched: Add support for HW offloading for CBS") Signed-off-by:

[ 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.

[ 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:

[ 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.

[ 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.

[ Upstream commit d29f5aa0 ] So far we effectively clear the BMCR register. Some PHY's can deal with this (e.g. because they reset BMCR to a default as part of a soft-reset) whilst on others this causes issues because e.g. the autoneg bit is cleared. Marvell is an example, see also thread [0]. So let's be a little bit more gentle and leave all bits we're not interested in as-is. This change is needed for PHY drivers to properly deal with the original patch.

[ Upstream commit dce47aed ] When updated IDs on f842c41a ("amlogic: meson-gx-socinfo: Update soc ids") we introduced packages ids using the full 8bit value, but in the function socinfo_to_package_id() the id was filtered with the 0xf0 mask. While the 0xf0 mask is valid for most board, it filters out the lower 4 bits which encodes some characteristics of the chip. This patch moves the mask into the meson_gx_package_id table to be applied on each package name independently and add the correct mask for some specific entries. An example is the S905, in the vendor code the S905 is package_id different from 0x20, and S905M is exactly 0x20. Another example are the The Wetek Hub & Play2 boards using a S905-H variant, which is the S905 SoC with some licence bits enabled. These licence bits are encoded in the lower 4bits, so to detect the -H variant, we must detect the id == 0x3 with the 0xf mask.
