2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-02-17soc/mediatek: dsi: Increase pcw precisionYu-Ping Wu
When configuring MIPI DSI Tx, the value of pcw was calculated from data rate in MHz, leading to loss of precision. This patch changes to use data rate in Hz for the calculation so that the resulting value should be consistent with the one in kernel (CL:1786327). In addition, change the type of data rate to u32, and calculation of data rate from pixel clock is changed to use DIV_ROUND_UP for consistency with kernel (CL:1761843). Also remove unused variable txdiv.

2019-12-04Change all clrsetbits_leXX() to clrsetbitsXX()Julius Werner
This patch changes all existing instances of clrsetbits_leXX() to the new endian-independent clrsetbitsXX(), after double-checking that they're all in SoC-specific code operating on CPU registers and not actually trying to make an endian conversion. This patch was created by running sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g' across the codebase and cleaning up formatting a bit.

2019-08-13soc/mediatek: dsi: Refactor MIPI TX configurationHung-Te Lin
The only platform-specific difference in mtk_dsi_phy_clk_setting is how to configure MIPI TX because those registers (and logic) are quite different across different SOCs. The calculation of data rate is actually the same so we should isolate it and move to common, and rename mtk_dsi_phy_clk_setting to a better name as mtk_dsi_configure_mipi_tx.

2017-04-25mediatek/mt8173: Add support for Dual DSI outputJitao Shi
The MT817x display output pipeline can be configured to drive an 8-lane MIPI/DSI panel using "dual DSI" mode. For the "dual DSI" video data path, the UFO block is configured to reorder the data stream into left and right halves which are then sent by the SPLIT1 block to the DSI0 and DSI1 respectively. The DSI0 and DSI1 outputs are then synchronously clocked at half the nominal data rate by their respective MIPI_TX0/MIPI_TX1 phys. Also, update the call sites in oak mainboard to avoid build breakage.

2016-07-26meditek/mt8173: dsi: set mipi pin driving control onJitao Shi
We set this driving control to prevent signal attenuation caused by LVDS DRV termination. When DA_LVDSTX_PWR_ON is not set, LVSH has no power and LVDS DRV termination status is unknown (floating). This creates a chance that MIPI output would be influenced. The DSI's LP signal will be half voltage attenuation. There will be no display on panel. When DA_LVDSTX_PWR_ON is set, LVSH and LVDS DRV termination are effective and termination is fixed OFF. The DSI won't be influenced. We only need to set this register once, so we set it here to prevent repeatedly setting in the kernel when the system goes to recovery mode.
