This is a note to let you know that I've just added the patch titled spi: qup: support using GPIO as chip select line to the 6.0-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: spi-qup-support-using-gpio-as-chip-select-line.patch and it can be found in the queue-6.0 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 9506c74f56bccca8bac58f17a03084942ef4a7cf Author: Robert Marko <robert.marko@xxxxxxxxxx> Date: Thu Oct 6 21:48:19 2022 +0200 spi: qup: support using GPIO as chip select line [ Upstream commit b40af6183b685b0cf7870987b858de0d48db9ea0 ] Most of the device with QUP SPI adapter are actually using GPIO-s for chip select. However, this stopped working after ("spi: Retire legacy GPIO handling") as it introduced a check on ->use_gpio_descriptors flag and since spi-qup driver does not set the flag it meant that all of boards using GPIO-s and with QUP adapter SPI devices stopped working. So, to enable using GPIO-s again set ->use_gpio_descriptors to true and populate ->max_native_cs.
