Dan Carpenter	0613de3737	clk: davinci: cfgchip: testing the wrong variable There is a copy and paste bug here. We should be testing "usb1" instead of "usb0".

Kees Cook	0ed2dd03b9	treewide: Use struct_size() for devm_kmalloc() and friends 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>	2018-06-06 11:15:43 -07:00
David Lechner	58e1e2d2cd	clk: davinci: cfgchip: Add TI DA8XX USB PHY clocks This adds a new driver for the USB PHY clocks in the CFGCHIP2 syscon register on TI DA8XX-type SoCs. The USB0 (USB 2.0) PHY clock is an interesting case because it calls clk_enable() in a reentrant way. The USB 2.0 PSC only has to be enabled temporarily while we are locking the PLL, which takes place during the clk_enable() callback.
