* clk: zynqmp: Fix memory allocation in zynqmp_clk_setupGustavo A. R. Silva2019-01-091-2/+2
| | | | | | | | | | | | | | Fix memory allocation and use struct_size() in kzalloc(). This also fixes the allocation size to be correct, and smaller, because before we were allocating a bunch of sizeof(struct clk_hw_onecell_data) structures for each struct clk_hw we needed.

* clk: zynqmp: Off by one in zynqmp_is_valid_clock()Dan Carpenter2018-12-031-1/+1
| | | | | | | | | | | | The > comparison should be >= to prevent reading beyond the end of the clock[] array. (The clock[] array is allocated in zynqmp_clk_setup() and has clock_max_idx elements.)

* clk: zynqmp: handle fixed factor param query errorRajan Vaja2018-11-141-0/+3
| | | | | | | | | | Return proper error code in case query for fixed factor parameter fails. This also fixes build warning for set but not used variable 'ret'.

* drivers: clk: Add ZynqMP clock driverJolly Shah2018-10-098-0/+1635
This patch adds CCF compliant clock driver for ZynqMP. Clock driver queries supported clock information from firmware and regiters pll and output clocks with CCF.
