Improve documentation for the (H)SCIF Serial Port Register: - Make it clear the RTS and CTS lines are active-low, - Document the bits related to the serial port's clock pin. Signed-off-by:

Enhance the Renesas SCI UART driver to add support for GPIO-controlled modem lines (CTS, DSR, DCD, RNG, RTS, DTR), using the serial_mctrl_gpio helpers. GPIO-controlled modem lines can be used when dedicated modem lines are not available. Invalid configurations specifying both GPIO RTS/CTS and dedicated RTS/CTS are rejected. Signed-off-by:

Geert Uytterhoeven authored
Documentation/serial/driver clearly states: If the port does not support CTS, DCD or DSR, the driver should indicate that the signal is permanently active. Hence always set TIOCM_CTS, as we currently don't look at the CTS hardware line state at all. FWIW, this fixes the transmit path when hardware-assisted flow control is enabled, and userspace enables CRTSCTS. The receive path is still broken, as RTS is never asserted. Signed-off-by:

Some Renesas SCIF UARTs have dedicated lines for RTS/CTS hardware flow control. Whether these lines exist depends on SoC and UART instance inside the SoC. Whether these lines can be used for hardware flow control depends on board wiring. Amend the DT bindings with an optional property to indicate that RTS/CTS hardware flow control lines exist, and can be used as such, according to the Generic Serial DT Bindings. Signed-off-by:

This patch fixes a non-booting issue in Mainline. When booting with a compressed kernel, we need to be careful how we populate memory close to DDR start. AUTO_ZRELADDR is enabled by default in multi-arch enabled configurations, which place some restrictions on where the kernel is placed and where it will be uncompressed to on boot. AUTO_ZRELADDR takes the decompressor code's start address and masks out the bottom 28 bits to obtain an address to uncompress the kernel to (thus a load address of 0x42000000 means that the kernel will be uncompressed to 0x40000000 i.e. DDR START on this platform). Even changing the load address to after the co-processor's shared memory won't render a booting platform, since the AUTO_ZRELADDR algorithm still ensures the kernel is uncompressed into memory shared with the first co-processor (0x40000000). Another option would be to move loading to 0x4A000000, since this will mean the decompressor will decompress the kernel to 0x48000000. However, this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of memory would essentially be wasted for no good reason. Until we can work with ST to find a suitable memory location to relocate co-processor shared memory, let's disable the shared memory nodes. This will ensure a working platform in the mean time. NB: The more observant of you will notice that we're leaving the DMU shared memory node enabled; this is because a) it is the only one in active use at the time of this writing and b) it is not affected by the current default behaviour which is causing issues.
