2022-02-25serial: mvebu-uart: implement support for baudrates higher than 230400 BdPali Rohár
Implement simple usage of fractional divisor. When main divisor D is too large to represent requested baudrate then use divisor M from the fractional divisor feature. All the M prescalers are set to the same and maximal value 63, so the fractional part of the fractional divisor is not used at all. We also determine upper limit for possible baudrates. Experiments show that UART at baudrate 1500000 Bd with this configuration is stable. So there is no need to implement complicated calculation of fractional coefficients yet. To use this feature with higher baudrates, it is required to use UART clock provided by UART clock driver. Default boot xtal clock is not capable of higher baudrates.

2022-02-25serial: mvebu-uart: implement UART clock driver for configuring UART base clockPali Rohár
Implement a new device driver for controlling UART clocks on Marvell Armada 3700 SoC. This device driver is loaded for devices which match the compatible string "marvell,armada-3700-uart-clock". There are more pitfalls related to UART clocks: - both UARTs use same parent clock source (which can be xtal or one of the TBG clocks), - if a TBG clock is used as the parent clock, there are two additional divisors that can both be configured to divide the rate by 1, 2, ... 6, but these divisors are again shared between the two UART controllers on the SOC, - the configuration of the parent clock source and divisors is done in the address space of the first UART controller, UART1. Clocks can be gated separately for UART1 and UART2, but this setting also lives in the address space of UART1, - Marvell's Functional Specification for Armada 3720 document has the clock gating bits swapped, so the one described to gate UART1 clock actually gates UART2 and vice versa, - each UART has it's own "special divisor", and this uses the parent clock described above. These divisors are configure in each UART's address space separately. Thus the driver for UART2 controller needs to have access to UART1 address space, since UART1 address space contains some bits exclusive for UART2 and also some bits which are shared between UART1 and UART2. Also, during boot, when early console is active on one of the UARTs, and we want to switch parent clock from xtal (default) to TBG (to be more flexible with baudrates), the driver changing UART clocks also needs to be able to change the "special divisor", so that the baudrate of earlycon is not changed when swtiching to normal console. Thus the clock driver also needs to be able to access UART2 register space, for UART2's "special divisor". For these reasons, this new UART clock driver does not use ioremap_resource(), but only ioremap() to prevent resource conflicts between UART clock driver and UART driver. We need to share only two 32-bit registers between the UART driver and the UART clock driver: - UART Clock Control - UART 2 Baud Rate Divisor Access to these two registers are protected by one spinlock to prevent any conflicts. Access is required only during probing, when changing baudrate or during suspend/resume. Hardware can be configured to use one of following clocks as UART parent clock: TBG-A-P, TBG-B-P, TBG-A-S, TBG-B-S, xtal. Not every clock is usable for higher buadrates. Any subset can be specified in the device-tree and the driver will choose the best one which also still supports the mandatory baudrate of 9600 Bd. For smooth boot log output it is needed to specify clock used by early console, otherwise garbage would be printed on UART during probe of UART clock driver and transitioning from early console to normal console. We are implementing this to be able to configure TBG clock as UART parent clock, which is required to be able to achieve higher baudrates than 230400 Bd. We achieve this by referencing this new UART clock device node in UART's device node. UART clock device driver automatically chooses the best clock source for UART driver. Until now, UART's device-tree node needed to reference one of the static clocks (xtal or one of the TBGs) as parent clock in the `clocks` phandle - the parent clock which was configured before booting the kernel. If bootloader changed UART's parent clock, it needed to change the `clocks` phandle in DTB correspondingly before booting. From now on both the old mechanism (xtal or TBG referenced as parent clock in `clocks` phandle) and the new one (UART clock referenced in the `clocks` phandle) are supported, to provide full backward compatibility with existing DTS files, full backward compatibility with existing boot loaders, and to provide new features (runtime clock configuration to allow higher baudrates than 230400 Bd). New features are available only with new DTS files. There was also a discussion about how the UART node and the clock-controller node could be wrapped together in a new binding [1, 2]. As explained there, this is not possible if we want to keep backwards compatibility with existing bootloaders, and thus we are doing this by putting the UART clock-controller node inside the UART1 node.

2022-02-21serial: 8250_aspeed_vuart: add PORT_ASPEED_VUART port typeZev Weiss
Commit 54da3e381c2b ("serial: 8250_aspeed_vuart: use UPF_IOREMAP to set up register mapping") fixed a bug that had, as a side-effect, prevented the 8250_aspeed_vuart driver from enabling the VUART's FIFOs. However, fixing that (and hence enabling the FIFOs) has in turn revealed what appears to be a hardware bug in the ASPEED VUART in which the host-side THRE bit doesn't get if the BMC-side receive FIFO trigger level is set to anything but one byte. This causes problems for polled-mode writes from the host -- for example, Linux kernel console writes proceed at a glacial pace (less than 100 bytes per second) because the write path waits for a 10ms timeout to expire after every character instead of being able to continue on to the next character upon seeing THRE asserted. (GRUB behaves similarly.) As a workaround, introduce a new port type for the ASPEED VUART that's identical to PORT_16550A as it had previously been using, but with UART_FCR_R_TRIG_00 instead to set the receive FIFO trigger level to one byte, which (experimentally) seems to avoid the problematic THRE behavior.
