Subject: [PATCH resend 0/2] spi: add driver for ar934x spi controller
Date: Thu, 6 Feb 2020 16:44:41 +0800 [thread overview]
Message-ID: <20200206084443.209719-1-gch981213@gmail.com> (raw)
This controller is a superset of the already supported qca,ar7100-spi.
Besides the bit-bang mode in spi-ath79.c, this new controller added
a new "shift register" mode, allowing faster spi operations.
This mode doesn't need all the bit-bang code in spi-ath79.c and needs
a different clock setup, so I decided to write a new driver for it
instead of extending current spi-ath79 driver.
Resend the patchset because I forgot to CC documentation maintainers
