The rtc's status register allows to determine if a 32k crystal is connected to keep the rtc running in low power states provided the corresponding fuse bits were blown correctly during production. (In case they were not, the right frequency can be stated in the device tree.) If there is no such crystal available force the 24 MHz XTAL clock to keep running to retain the right date and time. Otherwise use the crystal to save some power. It would be nice to only switch to the crystal when the XTAL clock is about to be disabled and keep the crystal off when unneeded because XTAL is always on while the chip is powered on. But as sudden power loss isn't detectable this is not save.

Some board designers, when running out of clock output pads, decide to (mis)use PWM output pads to provide a clock to external components. This driver supports this practice by providing an adapter between the PWM and clock bindings in the device tree. As the PWM bindings specify the period in the device tree, this is a fixed clock.

Having a board where the I2C bus locks up occasionally made it clear that the bus recovery in the i2c-davinci driver will only work on some boards, because on regular boards, this will only toggle GPIO lines that aren't muxed to the actual pins. The I2C controller on SoCs like da850 (and da830), Keystone 2 has the built-in capability to bit-bang its lines by using the ICPFUNC registers of the i2c controller. Implement the suggested procedure by toggling SCL and checking SDA using the ICPFUNC registers of the I2C controller when present. Allow platforms to indicate the presence of the ICPFUNC registers with a has_pfunc platform data flag and add optional DT property "ti,has-pfunc" to indicate the same in DT.

When the CONTINUE bit is set, the interrupt status we are polling to identify if a transaction has finished can be sporadic. Even though the transfer has finished, the interrupt status may erroneously indicate that there is still data in the FIFO. This behaviour causes random timeouts in large PIO transfers. Instead of using the CONTINUE bit to control the CS lines, use the SPI core's CS GPIO handling. Also, now that the CONTINUE bit is not being used, we can poll for the ALLDONE interrupt to indicate transfer completion.

由 Pavel Nakonechny 提交于
According to description in 'include/net/dsa.h', in cascade switches configurations where there are more than one interconnected devices, 'rtable' array in 'dsa_chip_data' structure is used to indicate which port on this switch should be used to send packets to that are destined for corresponding switch. However, dsa_of_setup_routing_table() fills 'rtable' with port numbers of the _target_ switch, but not current one. This commit removes redundant devicetree parsing and adds needed port number as a function argument. So dsa_of_setup_routing_table() now just looks for target switch number by parsing parent of 'link' device node. To remove possible misunderstandings with the way of determining target switch number, a corresponding comment was added to the source code and to the DSA device tree bindings documentation file. This was tested on a custom board with two Marvell 88E6095 switches with following corresponding routing tables: { -1, 10 } and { 8, -1 }.

Documentation: DT bindings: Tegra AHB: require the legacy base address for existing chips Per Stephen Warren, note in the Tegra AHB DT binding documentation that we specifically deprecate any attempt to use the IP block's actual hardware base address, and advocate the use of the legacy "off-by-four" address in the 'regs' property, for Tegra chips with existing upstream Linux DT files that include a Tegra AHB node. This patch updates the documentation accordingly. Changing the existing kernel DT data isn't under consideration because Linux kernel DT data policy is to preserve compatibility between newer DT data files and older kernels. However, this additional step of changing the documentation should discourage others from sending kernel patches to try to change the legacy kernel DT data. Furthermore, for out-of-tree software (such as bootloaders or other operating systems) that may rely on Linux kernel DT binding documentation as an ABI (but not the Linux kernel DT data itself), such a change may allow future convergence with the Linux kernel DT data without additional code changes.
