In preparation to support new Rockchip OTP memory devices with different clock configurations and register layout, extend rockchip_data struct with the related members: clks, num_clks, reg_read. Additionally, to avoid managing redundant driver data, drop num_clks member from rockchip_otp struct and update all references to point to the equivalent member in rockchip_data. Signed-off-by:

Broadcom's NVRAM contains MACs for Ethernet interfaces. Those MACs are usually base addresses that are also used for calculating other MACs. For example if a router vendor decided to use gmac0 it most likely programmed NVRAM of each unit with a proper "et0macaddr" value. That is a base. Ethernet interface is usually connected to switch port. Switch usually includes few LAN ports and a WAN port. MAC of WAN port gets calculated as relative address to the interface one. Offset varies depending on device model. Wireless MACs may also need to be calculated using relevant offsets. To support all those scenarios let MAC NVMEM cells be referenced with an index specifying MAC offset. Disallow additionalProperties while at it. Signed-off-by:

The devices on cdx could be bound to drivers with the device DMA managed by kernel drivers or user-space applications. As multiple devices can be placed in the same IOMMU group, the DMA on these devices must either be entirely under kernel control or userspace control.

This PFSM controls the operational modes of the PMIC: - STANDBY and LP_STANDBY, - ACTIVE state, - MCU_ONLY state, - RETENTION state, with or without DDR and/or GPIO retention. Depending on the current operational mode, some voltage domains remain energized while others can be off. This PFSM is also used to trigger a firmware update, and provides R/W access to device registers. See Documentation/misc-devices/tps6594-pfsm.rst for more information. Signed-off-by:

William Breathitt Gray authored
Exposes consumer library functions providing support for interfaces compatible with the venerable Intel 8254 Programmable Interval Timer (PIT). The Intel 8254 PIT first appeared in the early 1980s and was used initially in IBM PC compatibles. The popularity of the original Intel 825x family of chips led to many subsequent variants and clones of the interface in various chips and integrated circuits. Although still popular, interfaces compatible with the Intel 8254 PIT are nowdays typically found embedded in larger VLSI processing chips and FPGA components rather than as discrete ICs. A CONFIG_I8254 Kconfig option is introduced by this patch. Modules wanting access to these i8254 library functions should select this Kconfig option, and import the I8254 symbol namespace.

Alfonso Rodriguez authored
The Zynq platform has PCAP, ICAP and JTAG interfaces for configuring programmable logic (PL). The existing driver implementation uses the PCAP interface to configure the PL. Before switching the PL configuration interface from PCAP to ICAP make sure that all outstanding Transactions relevant to the PL configuration should be completed by the PCAP interface otherwise it may lead to PL configuration issues. This patch provides a required fix to ensure that all existing PL transactions are completed before switching from PCAP to ICAP. For detailed information relevant to PL configuration interfaces refer Zynq 7000 TRM (section 6.5.1). Link: https://docs.xilinx.com/v/u/en-US/ug585-Zynq-7000-TRMSigned-off-by:
