See BSP commit 1f83a133b853138fad712d0a08a7689aac1e0183 ("Disable SPI flash via RPC") - done - SCIF - SCIF 0+3 can be muxed to FTDI chips, SCIF1 to MSIOF headers using an external FTDI, SCIF4 maybe via unpopulated I2C header - all SCIFs could be tested, patches sent - patches merged - done - SD/MMC - eMMC enabled and works, microSD enabled but still needs testing - first patches sent, only final DTS addition kept until testing is done - SD0H support was missing, resend needed - eMMC works but is too slow compared to BSP, investigation needed - microSD fails the same way the BSP does - Shimoda-san researched that this is because SW6 needs to select the proper voltage - SW is under the heat sink, though. So, for upstream only eMMC is desired - resend patches to enable eMMC only - slower speed than BSP moved to separate task - slower speed was because of wrong kernel config, upstream kernel is actually faster - THS/CIVM - first version sent - patch to improve logging needed more versions but we now came to a conclusion - binding documentation needed more versions to handle the differences between all SoCs - all patches merged - done - TMU - probably possible; pinmux to TCLK1-4 and check via non-populated I2C header on breakout board - enablement patches sent out - all other devices are in the control domain which we do not handle. Only the application domain is our job. - for a domain overview, check '001_R-CarS4_Bus Architecture_Rev0p70.pptx' (attachment in the S4 docs)
