The native CS may not support the SPI_CS_HIGH, so they should not be setup automatically. = With this patch the setting is done only for the CS that will use a GPIO as CS = Fixes: f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs= ") Cc: Signed-off-by: Gregory CLEMENT Link: https://lore.kernel.org/r/20191018152929.3287-1-gregory.clement@b= ootlin.com Signed-off-by: Mark Brown diff --git a/drivers/spi/spi.c b/drivers/spi/spi.c index f8b4654a57d3..d07517151340 100644 --- a/drivers/spi/spi.c +++ b/drivers/spi/spi.c @@ -1711,15 +1711,7 @@ static int of_spi_parse_dt(struct spi_controller *ct= lr, struct spi_device *spi, spi->mode |=3D SPI_3WIRE; if (of_property_read_bool(nc, "spi-lsb-first")) spi->mode |=3D SPI_LSB_FIRST; - - /* - * For descriptors associated with the device, polarity inversion is - * handled in the gpiolib, so all chip selects are "active high" in - * the logical sense, the gpiolib will invert the line if need be. - */ - if (ctlr->use_gpio_descriptors) - spi->mode |=3D SPI_CS_HIGH; - else if (of_property_read_bool(nc, "spi-cs-high")) + if (of_property_read_bool(nc, "spi-cs-high")) spi->mode |=3D SPI_CS_HIGH; = /* Device DUAL/QUAD mode */ @@ -1783,6 +1775,14 @@ static int of_spi_parse_dt(struct spi_controller *ct= lr, struct spi_device *spi, } spi->chip_select =3D value; = + /* + * For descriptors associated with the device, polarity inversion is + * handled in the gpiolib, so all gpio chip selects are "active high" + * in the logical sense, the gpiolib will invert the line if need be. + */ + if ((ctlr->use_gpio_descriptors) && ctlr->cs_gpiods[spi->chip_select]) + spi->mode |=3D SPI_CS_HIGH; + /* Device speed */ rc =3D of_property_read_u32(nc, "spi-max-frequency", &value); if (rc) { ---------------------------------------------------------------------------= ---- Git bisection log: ---------------------------------------------------------------------------= ---- git bisect start # good: [7d194c2100ad2a6dded545887d02754948ca5241] Linux 5.4-rc4 git bisect good 7d194c2100ad2a6dded545887d02754948ca5241 # bad: [e025ec2b58a56f29813afe3b5a8b9d0170c84eb3] Merge remote-tracking bra= nch 'spi/topic/ptp' into spi-next git bisect bad e025ec2b58a56f29813afe3b5a8b9d0170c84eb3 # good: [6c613f68aabf33385c01e949204ac5ed30887161] spi: core,atmel: convert= `word_delay_usecs` -> `word_delay` for spi_device git bisect good 6c613f68aabf33385c01e949204ac5ed30887161 # good: [585d18f7ebd1dba7400dcc7189a5f7223b821374] spi: atmel: Configure GP= IO per CS instead of by controller git bisect good 585d18f7ebd1dba7400dcc7189a5f7223b821374 # good: [e58f7d15e6beb255b3907054a0536db77c979a31] spi: xilinx: Add DT supp= ort for selecting transfer word width git bisect good e58f7d15e6beb255b3907054a0536db77c979a31 # bad: [fed8d8c7a6dc2a76d7764842853d81c770b0788e] spi: atmel: fix handling = of cs_change set on non-last xfer git bisect bad fed8d8c7a6dc2a76d7764842853d81c770b0788e # bad: [3e5ec1db8bfee845d9f8560d1c64aeaccd586398] spi: Fix SPI_CS_HIGH sett= ing when using native and GPIO CS git bisect bad 3e5ec1db8bfee845d9f8560d1c64aeaccd586398 # good: [b2662a164f9dc48da8822e56600686d639056282] spi: pxa2xx: Set control= ler->max_transfer_size in dma mode git bisect good b2662a164f9dc48da8822e56600686d639056282 # first bad commit: [3e5ec1db8bfee845d9f8560d1c64aeaccd586398] spi: Fix SPI= _CS_HIGH setting when using native and GPIO CS ---------------------------------------------------------------------------= ----
