2024-03-09clk: zynq: Prevent null pointer dereference caused by kmalloc failureDuoming Zhou1-5/+3
The kmalloc() in zynq_clk_setup() will return null if the physical memory has run out. As a result, if we use snprintf() to write data to the null address, the null pointer dereference bug will happen. This patch uses a stack variable to replace the kmalloc().

Use BIT() where makes sense. This alings usage of bit operations in the same pieces of code. Moreover, strictly speaking by the letter of the C standard, left shift of 1 by 31 bits is UB (undefined behaviour), switching to BIT() addresses that as well.

CLK_INFRA_SSPM_32K_SELF has the "f_f26m_ck" clock assigned as its parent.

2024-02-22clk: hisilicon: Use devm_kcalloc() instead of devm_kzalloc()Erick Archer1-2/+1
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific devm_kcalloc() function instead of the argument size * count in the devm_kzalloc() function.

2024-01-23clk: renesas: cpg-mssr: Ignore all clocks assigned to non-Linux systemKuninori Morimoto1-7/+104
Some boards might use Linux and another OS at the same time. In such case, currently, during booting, Linux will stop necessary module clocks which are not used on the Linux side, but are used by another OS. To avoid such situation, renesas-cpg-mssr tries to find status = "reserved" devices (A), and adds CLK_IGNORE_UNUSED flag to its <&cgp CPG_MOD xxx> clock (B). Table 2.4: Values for status property https://github.com/devicetree-org/devicetree-specification/releases/download/v0.4/devicetree-specification-v0.4.pdf "reserved" Indicates that the device is operational, but should not be used. Typically this is used for devices that are controlled by another software component, such as platform firmware. ex) scif5: serial@e6f30000 { ... (B) clocks = <&cpg CPG_MOD 202>, <&cpg CPG_CORE R8A7795_CLK_S3D1>, <&scif_clk>; ...
