This allows to have a clock on clko even if the controller is disabled. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>

2020-02-09can: mcp25xxfd: allow building without debugfs functionalityMax Krummenacher
If CONFIG_CAN_MCP25XXFD_DEBUG_FS is not defined but CONFIG_DEBUG_FS is then the code fails to compile. Fix this by conditionally compile on CONFIG_CAN_MCP25XXFD_DEBUG_FS. CONFIG_CAN_MCP25XXFD_DEBUG_FS depends on CONFIG_DEBUG_FS, there is no need to test for both. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>

In case of predicted DLC=15 and in case at least 33% of those are sent via BRS be aggressive and use bulk fifo reads to avoid missing any frames due to releasing FIFOs not as fast as possible.

Allow prediction of can frame sizes based on the last 32 Can Frames received. Naive histogram approach hast been taken for now.

It should be possible to take this prediction to use bulk reads for CanFD as well when we have a prediction of length of 48 or 64.

2020-02-09can: mcp25xxfd: optimize SPI reads of FIFOs in can2.0 modeMartin Sperl
To reduce the amount of spi_messages send this patch optimizes the read of RX fifos so that multiple Fifos are read together. This only works well in CAN2.0 mode where the overhead of prefetching 8 bytes (even if the actual length is 0) is negligable compared to the SPI-framework overhead. Statistics in debugfs show for 1000000 DLC=0 can messages received: ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads <== 355411 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_1 <== 92778 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_2 <== 7133 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_3 <== 130390 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_4 <== 123807 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_5 <== 1266 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_6 <== 34 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_7 <== 1 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_bulk_reads_8+ <== 0 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/rx_reads <== 999999 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/int_system_error <== 1 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/int_system_error_rx <== 1 ==> /sys/kernel/debug/mcp25xxfd-spi0.0/can/stats/int_system_error_tx <== 0 There was one SERR error where we lost one can frame during the handling of the error condition. So to read all of those 999999 RX fifos we formerly have scheduled 999999 spi_messages. With this patch we have only scheduled 355411 spi_messages, so only 35.5% of the former value. This also means we have not been transferring 1289176 (=2*(999999-355411)) unnecessary command bytes over the SPI bus. As we have been issuing less SPI transfers reading SRAM this also has reduced the likleyhood of SERR happening - it does not solve the complete issue as seen above.

While with this patch we have only scheduled 44691 spi_messages, so only 44.6% of the former value.

Add un-optimized Can2.0 and CanFD transmission support. On a Rpi3 we can saturate the CAN bus at 1MHz transmitting Can2.0 frames with DLC=0 for the number of configured tx-fifos. Afterwards we need some time to recover the state before we can fill in the fifos again. With 7 tx fifos we can: send those 7 frames in 0.33ms and then we wait for 0.26ms so that is a 56% duty cycle. With 24 tx fifos this changes to: 1.19ms for 24 frames and then we wait for 0.52ms so that is a 70% duty cycle. -- Changelog: V6 -> V7: added can transmission into a separate patch to reduce the size of the individual patches to make the linux-can mailing-list happy...

2020-02-09arm64: dts: apalis-imx8x: fix device tree compilation issueMarcel Ziswiler
This fixes the following device tree compilation issue as introduced by the previous commit 621db2fdb2e1 ("arm64: dts: apalis-imx8x: add adv7280 to devicetree"): DTC arch/arm64/boot/dts/freescale/fsl-imx8qxp-apalis-eval.dtb arch/arm64/boot/dts/freescale/fsl-imx8qxp-apalis-eval.dtb: ERROR (phandle_references): Reference to non-existent node or label "adv7280_ep" Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

2020-02-09ARM: dts: colibri-imx6ull: correct wrong pinmuxing and add commentsPhilippe Schenker
Some pinmuxings are obviously wrong, originating from a copy/paste error. This patch corrects that with the following strategy: - Set all reserved bits to zero - Leave drive strength and slew rate as is - Add sensible pull and hysteresis depending on the function of the pin - Not used pins are muxed to their reset-value defined by the SoC Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
