* lspcon_i2c_spi.c: Clean up some unnecessary indirectionEdward O'Callaghan2020-04-191-11/+7
| | | | | | | | | | | | | | | | | | Clean up some confusion of implicit copies by indirection. This allows the caller of register_spi_master() to have it's internal state in the expected way. Also add an error when the mpu reset fails on init.

* lspcon_i2c_spi.c: Add SPI-master support for PS17{5,6}Shiyu Sun2020-04-011-0/+505
This adds support for the Parade lspcon usb-c to HDMI protocol translater part that is i2c-controlled. The support allows the host to reach the SPI ROM that hangs off the part where it stores its firmware. Usage is as follows: flashrom -p lspcon_i2c_spi:bus=X where X is the bus number. BUG=b:148746232 BRANCH=none TEST=tested with following commands, read/write/erase works good. flashrom -p lspcon_i2c_spi:bus=7 -r /tmp/foo; flashrom -p lspcon_i2c_spi:bus=7 -E; flashrom -p lspcon_i2c_spi:bus=7 -w /tmp/foo; Change-Id: I039e683252cfaf1ffef8694a3e8081b1b6b944f7 Signed-off-by: Shiyu Sun <sshiyu@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/39687 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org>
