* ipmi: add an NPCM7xx KCS BMC driverHaiyue Wang2018-05-181-0/+39
| | | | | | | | | | | | | | This driver exposes the Keyboard Controller Style (KCS) interface on Novoton NPCM7xx SoCs as a character device. Such SOCs are commonly used as a BaseBoard Management Controller (BMC) on a server board, and KCS interface is commonly used to perform the in-band IPMI communication between the server and its BMC.

* ipmi: add an Aspeed KCS IPMI BMC driverHaiyue Wang2018-05-181-0/+25
| | | | | | | | | | | | | | | The KCS (Keyboard Controller Style) interface is used to perform in-band IPMI communication between a server host and its BMC (BaseBoard Management Controllers). This driver exposes the KCS interface on ASpeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are commonly used as BMCs and this driver implements the BMC side of the KCS interface.

|\ | | | | | | | | | | | | | | | | | | This is the DRM tree that was merged into the mainline 4.14 kernel. The ASPEED GFX DRM driver requires functionaliy that was included in this tree, so we merge it back into the 4.13 OpenBMC tree. This should have no impact on other parts of the BMC.

Also document properly that drm_vblank_cleanup is optional, the core calls this already. v2: Make it clear that cleanup happens in drm_dev_fini for drivers with their own ->release callback (Thierry).

We request a shared reset controller each time a bus driver is loaded, as the reset is shared between the 14 i2c buses. On remove the reset is asserted, which only touches the hardware once the last i2c bus is removed. The reset is required as the I2C buses will not work without releasing the reset. Previously the driver only worked with out of tree hacks that released this reset before the driver was loaded. Update the device tree bindings to reflect this.

For example, external mode is selected by a user when an external debug device is attached to the FSI pins. To do this, we need to set specific states for the trans, mux and enable gpios, and prevent access to clk & data from the FSI core code (by returning EBUSY). External mode is controlled by a sysfs attribute, so add the relevent information to Documentation/ABI/ OpenBMC-Staging-Count: 2 Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Reviewed-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Joel Stanley <joel@jms.id.au>
