clk: move clk-ti-sci driver to 'ti' directory

2021-01-12T05:28:05+00:00

The patch moves the clk-ti-sci.c file to the 'ti' directory along with
all the other TI's drivers, and renames it clk-sci.c.

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46+00:00

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

clk: Rename free() to rfree()

2020-02-06T02:33:46+00:00

This function name conflicts with our desire to #define free() to
something else on sandbox. Since it deals with resources, rename it to
rfree().

clk: sci-clk: add slack to clk-set-rate passed to firmware

2020-01-20T04:40:29+00:00

Add slack to the clock frequency parameters passed to firmware within
clk_set_rate. min-freq is changed to 0 and max-rate is changed to
ULONG_MAX. This fixes certain issues with pll clock rounding when the
firmware is not able to set the frequency exactly to the target, the
current implementation fails if the available frequency is even 1Hz off
the target. With the change, the firmware still tries its best to set
the frequency as close as possible to the target.

clk: Introduce TI System Control Interface (TI SCI) clock driver

2018-09-11T12:32:55+00:00

Some TI Keystone 2 and K3 family of SoCs contain a system controller
(like the Power Management Micro Controller (PMMC) on 66AK2G SoCs and
the Device Management and Security Controller on AM65x SoCs) that manage
the low-level device control (like clocks, resets etc) for the various
hardware modules present on the SoC. These device control operations are
provided to the host processor OS through a communication protocol
called the TI System Control Interface (TI SCI) protocol.

This patch adds a clock driver that communicates to the system
controller over the TI SCI protocol for performing clock management of
various devices present on the SoC. Various clock functionality is
achieved by the means of different TI SCI device operations provided by
the TI SCI framework.

This code is loosely based on the drivers/clk/keystone/sci-clk.c driver
of the Linux kernel.
