| 2019-08-12 | firmware: arm_scmi: Drop config flag in clk_ops->rate_set | Sudeep Holla | |
| CLOCK_PROTOCOL_ATTRIBUTES provides attributes to indicate the maximum number of pending asynchronous clock rate changes supported by the platform. If it's non-zero, then we should be able to use asynchronous clock rate set for any clocks until the maximum limit is reached. In order to add that support, let's drop the config flag passed to clk_ops->rate_set and handle the asynchronous requests dynamically.

| 2018-08-30 | clk: Convert to using %pOFn instead of device_node.name | Rob Herring | |
| In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier.

| 2018-08-02 | clk: scmi: Fix the rounding of clock rate | Amit Daniel Kachhap | |
| This fix rounds the clock rate properly by using quotient and not remainder in the calculation. This issue was found while testing HDMI in the Juno platform.

| 2018-06-06 | treewide: Use struct_size() for devm_kmalloc() and friends | Kees Cook | |
| Replaces open-coded struct size calculations with struct_size() for devm_*, f2fs_*, and sock_* allocations. Automatically generated (and manually adjusted) from the following Coccinelle script: // Direct reference to struct field. @@ identifier alloc =~ "devm_kmalloc|devm_kzalloc|sock_kmalloc|f2fs_kmalloc|f2fs_kzalloc"; expression HANDLE; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(HANDLE, sizeof(*VAR) + COUNT * sizeof(*VAR->ELEMENT), GFP) + alloc(HANDLE, struct_size(VAR, ELEMENT, COUNT), GFP) // mr = kzalloc(sizeof(*mr) + m * sizeof(mr->map[0]), GFP_KERNEL); @@ identifier alloc =~ "devm_kmalloc|devm_kzalloc|sock_kmalloc|f2fs_kmalloc|f2fs_kzalloc"; expression HANDLE; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(HANDLE, sizeof(*VAR) + COUNT * sizeof(VAR->ELEMENT[0]), GFP) + alloc(HANDLE, struct_size(VAR, ELEMENT, COUNT), GFP) // Same pattern, but can't trivially locate the trailing element name, // or variable name. @@ identifier alloc =~ "devm_kmalloc|devm_kzalloc|sock_kmalloc|f2fs_kmalloc|f2fs_kzalloc"; expression HANDLE; expression GFP; expression SOMETHING, COUNT, ELEMENT; @@ - alloc(HANDLE, sizeof(SOMETHING) + COUNT * sizeof(ELEMENT), GFP) + alloc(HANDLE, CHECKME_struct_size(&SOMETHING, ELEMENT, COUNT), GFP) Signed-off-by: Kees Cook <keescook@chromium.org> | |||
| 2018-03-20 | clk: scmi: use devm_of_clk_add_hw_provider() API and drop scmi_clocks_remove | Sudeep Holla | |
| Commit aa795c41d9cd ("clk: Add devm_of_clk_add_hw_provider()/del_provider() APIs") adds devm_of_clk_add_hw_provider which takes care of deleting the clock provider when the clock providers device is removed. This patch makes use of devm_of_clk_add_hw_provider() instead of of_clk_add_hw_provider() so that we can eliminate the need of explicit scmi_clocks_remove for just doing of_clk_del_provider() Acked-by: Stephen Boyd <sboyd@kernel.org> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> | |||
| 2018-02-28 | clk: add support for clocks provided by SCMI | Sudeep Holla | |
| On some ARM based systems, a separate Cortex-M based System Control Processor(SCP) provides the overall power, clock, reset and system control. System Control and Management Interface(SCMI) Message Protocol is defined for the communication between the Application Cores(AP) and the SCP. This patch adds support for the clocks provided by SCP using SCMI protocol.
