2020-05-28ARM: dts: imx6-apalis: add gpio-line-namesMax Krummenacher
Add GPIO line names on module level. Those are all GPIOs which a user might use on his custom carrier board. If more meaningful names are available on the carrier board, the user can overwrite the line names in the carrier board level device tree.

2020-05-26ARM64: dts: keep hub control signals reset pull stateMax Krummenacher
RESET and CONNECT come out of reset with pull downs enabled. Keep that in the pin muxing. These pins are switched to output during the hub configuration and then controlled as needed. The datasheet specifically states that CONNECT must not be driven when RESET is low, so keeping the pull downs is less likely to violate the spec. The INT pin has an external pull up, so keeping the pull down makes the system draw more power. Related-to: ELB-2702 Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>

2020-05-07ARM: dts: imx7-colibri: add gpio-line-namesStefan Agner
Add Colibri SODIMM numbers as GPIO line names on module level. The GPIO lines with a name are all available on the SODIMM edge connector of the Colibri iMX7 module and therefore a customer might use it as a GPIO. The Toradex Evaluation Board has the SODIMM numbers printed on the silk- screen. This allows a customer to quickly control a GPIO on a pin-header by using the name printed next to it. Putting the GPIO line name on module level makes sure that a customer gets a reasonable default. If more meaningful names are available on a custom carrier board, the user can overwrite the line names in a carrier board level device tree. The eMMC based modules share all GPIO names except two GPIOs on bank 6 which are not available on the raw NAND devices. Hence overwrite GPIO line names of bank 6 in the eMMC specific device tree file.

ION CMA memory default is cacheable, need flush cache after memset(), else cache and physical memory not sync may cause problem. Issue case: VPU Video playback or GPU render have dirty line issue. Root cause: ION CMA allocate cacheable buffer and do memset(), some data still in cache not in physical memory, VPU or GPU write the buffer with physical address, or user call ion_mmap() to map the buffer through pgprot_writecombine() as no-cache and write the buffer, later some CPU cache access trigger cache flush, previous memset() data go to physical memory as dirty data.

2020-03-30ARM: dts: apalis-imx6qdl: use rgmii-id instead of rgmiiPhilippe Schenker
Until now a PHY-fixup in mach-imx set our rgmii timing correctly. For the PHY KSZ9131 there is no PHY-fixup in mach-imx. To support this PHY too, use rgmii-id. For the now used KSZ9031 nothing will change, as rgmii-id is only implemented and supported by the KSZ9131. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com> Signed-off-by: David S. Miller <davem@davemloft.net> (cherry picked from commit 1b68480b945e51ba879496d3f9ff5a5addd82007) We have a PHY-fixup in our downstream Linux. However this patch makes anyway sense to apply as it documents the rgmii mode properly and won't brake anything. Related-to: ELB-2581 Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
