2023-11-23serial: 8250: 8250_omap: Do not start RX DMA on THRI interruptRonald Wahl
Starting RX DMA on THRI interrupt is too early because TX may not have finished yet. This change is inspired by commit 90b8596ac460 ("serial: 8250: Prevent starting up DMA Rx on THRI interrupt") and fixes DMA issues I had with an AM62 SoC that is using the 8250 OMAP variant.

2023-11-23serial: sc16is7xx: improve regmap debugfs by using one regmap per portHugo Villeneuve
With this current driver regmap implementation, it is hard to make sense of the register addresses displayed using the regmap debugfs interface, because they do not correspond to the actual register addresses documented in the datasheet. For example, register 1 is displayed as registers 04 thru 07: $ cat /sys/kernel/debug/regmap/spi0.0/registers 04: 10 -> Port 0, register offset 1 05: 10 -> Port 1, register offset 1 06: 00 -> Port 2, register offset 1 -> invalid 07: 00 -> port 3, register offset 1 -> invalid ... The reason is that bits 0 and 1 of the register address correspond to the channel (port) bits, so the register address itself starts at bit 2, and we must 'mentally' shift each register address by 2 bits to get its real address/offset. Also, only channels 0 and 1 are supported by the chip, so channel mask combinations of 10b and 11b are invalid, and the display of these registers is useless. This patch adds a separate regmap configuration for each port, similar to what is done in the max310x driver, so that register addresses displayed match the register addresses in the chip datasheet. Also, each port now has its own debugfs entry. Example with new regmap implementation: $ cat /sys/kernel/debug/regmap/spi0.0-port0/registers 1: 10 2: 01 3: 00 ... $ cat /sys/kernel/debug/regmap/spi0.0-port1/registers 1: 10 2: 01 3: 00 As an added bonus, this also simplifies some operations (read/write/modify) because it is no longer necessary to manually shift register addresses.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove().

2023-11-23serial: sa1100: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void.
