From 13a2ef6cbd0838a7965914dda3b4a63ff4ae5440 Mon Sep 17 00:00:00 2001 From: Shiyu Sun Date: Thu, 19 Mar 2020 14:37:57 +1100 Subject: lspcon_i2c_spi.c: Add SPI-master support for PS17{5,6} 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 Reviewed-on: https://review.coreboot.org/c/flashrom/+/39687 Tested-by: build bot (Jenkins) Reviewed-by: Edward O'Callaghan --- meson_options.txt | 1 + 1 file changed, 1 insertion(+) (limited to 'meson_options.txt') diff --git a/meson_options.txt b/meson_options.txt index 28312716..a103dc60 100644 --- a/meson_options.txt +++ b/meson_options.txt @@ -35,3 +35,4 @@ option('config_satasii', type : 'boolean', value : true, description : 'SiI SATA option('config_serprog', type : 'boolean', value : true, description : 'serprog') option('config_usbblaster_spi', type : 'boolean', value : true, description : 'Altera USB-Blaster dongles') option('config_stlinkv3_spi', type : 'boolean', value : true, description : 'STMicroelectronics STLINK-V3') +option('config_lspcon_i2c_spi', type : 'boolean', value : false, description : 'Parade lspcon USB-C to HDMI protocol translator') -- cgit v1.2.3
