When consolidating the msm8660 GCC probe code I forgot to keep around these temporary clock registrations. Put them back so the clock tree is not entirely orphaned. Fixes: 49fc825f (clk: qcom: Consolidate common probe code) Signed-off-by:

With the addition of clock-indices, we need to change the renesas clock implementation to use these instead of the local definition of "renesas,clock-indices". Since this will break booting with older device trees, we add a simple auto-detection of which properties are present. Signed-off-by:

The C0(mpu_clk), C1(main_clk), and C2(dbg_base_clk) outputs from the main PLL go through a pre-divider before coming into the system. These registers were hidden for the CycloneV platform, but are now used for the ArriaV platform. This patch updates the clock driver to read the div-reg property for the socfpga-periph-clk clocks. Also moves the div_mask define to clk.h for re-use. Signed-off-by:

The APQ8064 and MSM8960 share a significant amount of clock data and code between the two SoCs. Rather than duplicating the data we just add support for a unqiue APQ8064 clock table into the MSM8960 code. For now add just enough clocks to get a basic serial port going on an APQ8064 device.

The next patch defines a binding for a new Broadcom SoC that uses Kona style CCUs for its clocks. Update the generic Kona clock binding document so it's more natural to accomodate the definitions of additional SoC families. Specifically: - Define the compatible string values generically, referring to specific per-model values later in the document. - Put the device tree example immediately after the required properties listing, before the tables of SoC-specific values. - Clearly identify the start of the section defining specific values related to the BCM281XX family - Add a list of the specific BCM281XX family compatible strings. - Reword the description of the table slightly.

The Broadcom 281xx clock code uses a #define for the compatible string for it's clock control units (CCUs). Rather than defining those in the C source file, define them in the header file that's shared by both the code and the device tree source file (along with all the clock ids). Signed-off-by:

Rather than "manually" setting up each CCU's clock entries at run time, define a flexible array of generic Kona clock structures within the CCU structure itself. Each of these entries contains generic kona clock information (like its CCU pointer and clock framework initialization data). Each also has a pointer to a structure contianing clock type-dependent initialization data (like register definitions). Since we'll iterate over these arrays we need to be sure they have slots for all potential clock index values. (E.g. for the root CCU we must have at least BCM281XX_ROOT_CCU_CLOCK_COUNT slots.) To ensure this we always define an extra entry and fill it using the special initializer LAST_KONA_CLK. Just about everything we need to know about a clock can be defined statically. As a result, kona_clk_setup() can be changed to take just a kona_clk structure as its argument, and peri_clk_setup() can be simplified. With the information pre-defined we are also able to handle most clock setup genericially. We can do away with the CCU-specific callback functions that previously were needed to set up the entries in CCU's clock array. Move the definition of the ccu_data structure down in "clk-kona.h" to avoid a forward dependency. Signed-off-by:

We know up front how many CCU's we'll support, so there's no need to allocate their data structures dynamically. Define a macro KONA_CCU_COMMON() to simplify the initialization of many of the fields in a ccu_data structure. Pass the address of a statically defined CCU structure to kona_dt_ccu_setup() rather than having that function allocate one. We also know at build time how many clocks a given CCU will provide, though the number of of them for each CCU is different. Record the number of clocks we need in the CCU's clk_onecell_data struct (which is used when we register the CCU with the common clock code as a clock provider). Rename that struct field "clk_data" (because "data" alone gets a little confusing). Use the known clock count to move the allocation of each CCU's clocks array into ccu_clks_setup() rather than having each CCU's setup callback function do it. (The real motivation behind all of this is that we'll be doing some static initialization of some additional CCU-specific data soon.) Signed-off-by:

As I developed the bcm281xx clock code I understood there were restrictions on device tree "compatible" strings names, and as a result "bcm11351" was used in places despite the part family being more properly called "bcm281xx". This can be a little confusing. In some cases I went to far and things using "bcm11351" when that was not necessary. This patch remedies this. It renames the symbol used to define the "compatible" string (but not its value) so it uses "BCM281XX". Similarly, the name names provided to the CLK_OF_DECLARE() macro are changed, hoping to minimize the number of places that the confusing "11351" string is used. Signed-off-by:
