This allows to allocate the right amount of memory to keep resets and clocks reference _ update the memory allocation for deasserted resets and enabled clocks reference list. Replace lists by arrays. v3: _ keep enabled clocks and deasserted resets reference in list in order to disable clock or assert resets in error path or in .remove callback _ add missing commit message _ use struct generic_ehci * instead of struct udevice * as parameter for ehci_release_resets() and ehci_release_clocks() _ test return value on generic_phy_get_by_index() and generic_phy_init() _ split previous patch 5 in 3 independant patch for CLOCK, RESET and PHY support v2: _ add needed reset_request() in RESET framework _ add error path in ehci/ohci-generic to disable clocks and to assert resets _ add .remove callback with clocks, resets and phy release _ split the replacement of printf() by error() in an independant patch Patrice Chotard (11): reset: add reset_request() reset: add reset_count() reset: add reset_assert_all() clk: add clk_count() clk: add clk_disable_all() usb: host: ehci-generic: replace printf() by error() usb: host: ehci-generic: add error path and .remove callback usb: host: ehci-generic: add generic PHY support usb: host: ohci-generic: add CLOCK support usb: host: ohci-generic: add RESET support usb: host: ohci-generic: add generic PHY support drivers/clk/clk-uclass.c | 34 ++++++++++ drivers/reset/reset-uclass.c | 44 +++++++++++++ drivers/usb/host/ehci-generic.c | 142 +++++++++++++++++++++++++++++++++------- drivers/usb/host/ohci-generic.c | 121 +++++++++++++++++++++++++++++++++- include/clk.h | 22 +++++++ include/reset.h | 37 +++++++++++ 6 files changed, 375 insertions(+), 25 deletions(-) -- 1.9.1
