spi: tools: Add include folder to .gitignore

2026-03-04T12:19:41+00:00

[ Upstream commit 5af56f30c4fcbade4a92f94dadfea517d1db9703 ] The Makefile for the SPI tools creates an include/linux/spi folder and some symlinks inside it. After running `make -C spi/tools`, this folder shows up as untracked in the git status. Add the above folder to the .gitignore file.

spi: spidev_test Add three missing spi mode bits

2023-05-30T14:20:12+00:00

Added the three missing spi mode bits SPI_3WIRE_HIZ, SPI_RX_CPHA_FLIP, and SPI_MOSI_IDLE_LOW. Signed-off-by: Boerge Struempfel Link: https://lore.kernel.org/r/20230530141641.1155691-6-boerge.struempfel@gmail.com Signed-off-by: Mark Brown

spi: spidev_test: Sorted the options into logical groups

2023-05-30T14:20:11+00:00

In order to increase usability, the command line options are sorted into logical groups. In addition, the usage string was sorted alphabetically, and the missing parameters '8','i' and 'o' were added. Furthermore, the option descriptions were moved further to the right, in order to allow for longer option names.

spi: spidev_test: Warn when the mode is not the requested mode

2022-06-13T14:56:03+00:00

Print a warning if the device mode doesn't match the requested mode. The user doesn't enter the mode in hex so it isn't obvious when setting the mode succeeds that the mode isn't the requested mode. The kernel logs a message, it will be more visible if the test also prints a warning. I was testing --quad, which is unsupported, but doesn't cause the mode request to fail.

kbuild: replace $(if A,A,B) with $(or A,B)

2022-02-15T03:25:56+00:00

$(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched. Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier

spi: tools: make a symbolic link to the header file spi.h

2021-04-22T15:30:39+00:00

The header file spi.h in include/uapi/linux/spi is needed for spidev.h, so we also need make a symbolic link to it to eliminate the error message as below: In file included from spidev_test.c:24: include/linux/spi/spidev.h:28:10: fatal error: linux/spi/spi.h: No such file or directory 28 | #include | ^~~~~~~~~~~~~~~~~ compilation terminated.

spi: spidev_test: Use %u to format unsigned numbers

2020-06-08T12:42:44+00:00

Consistently use %u to format unsigned numbers. For "bits" this doesn't matter that much, as it is "uint8_t". However, "speed" is "uint32_t", so in case people use "-s -1" to force the maximum, they would see: max speed: -1 Hz (4294967 KHz) While at it, use "k" (kilo) instead of "K" (kelvin) in "kHz".

spi: spidev_test: Remove hidden temporary file when make clean

2020-04-14T17:36:29+00:00

In the current code, it only removes *.o and .*.o.d file when make clean, there still exists useless .*.o.cmd file, just remove it. Without this patch: [yangtiezhu@linux spi]$ make [yangtiezhu@linux spi]$ make clean [yangtiezhu@linux spi]$ ls -1 .*.o.cmd .spidev_fdx-in.o.cmd .spidev_fdx.o.cmd .spidev_test-in.o.cmd .spidev_test.o.cmd With this patch: [yangtiezhu@linux spi]$ make [yangtiezhu@linux spi]$ make clean [yangtiezhu@linux spi]$ ls -1 .*.o.cmd ls: cannot access .*.o.cmd: No such file or directory Signed-off-by: Tiezhu Yang Link: https://lore.kernel.org/r/1586230512-5507-1-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Mark Brown
