Subject: [PATCH v2] clk: socfpga: fix iomem pointer cast on 64-bit
Pointers should be cast with uintptr_t instead of integer. This fixes
warning when compile testing on ARM64:
drivers/clk/socfpga/clk-gate.c: In function ‘socfpga_clk_recalc_rate’:
drivers/clk/socfpga/clk-gate.c:102:7: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
Fixes: b7cec13f082f ("clk: socfpga: Look for the GPIO_DB_CLK by its offset")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...onical.com>
Acked-by: Dinh Nguyen <dinguyen@...nel.org>

Changes since v1:
1. Add Fixes and Ack.
2. Use uintptr_t (Stephen Boyd).
