| * clk: imx: clk-pllv1: fix wrong PLL recalc on i.MX1/i.MX21Ahmad Fatoum2021-03-251-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding -Wtype-limits to the build correctly detects that the first branch (mfn < 0) is never taken as mfn is unsigned. Import the Linux v5.11 bits that correctly checks the sign of the sign/magnitude integer. Unlike Linux, we don't need to check whether it's an i.MX1 or i.MX21 here, because an #ifdef earlier normalizes the value to be aligned with the i.MX27's. This however means that a multi-image barebox wasn't and will remain not able to properly target both <= i.MX21 and newer SoCs at the same time. This is just build-time tested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The upstream implementation passes the clock's parent_names as an address of a local array to the core. That's ok because data contained in struct clk_init_data is duplicated and stored with a proper lifetime. We don't have that in barebox, so the clock providers themselves are responsible for allocating an array with suitable lifetime. Most at91 clk drivers did this by having a fixed size array in the clock's private data struct. Since 47475fa5e0e1 ("clk: at91: add sama5d2 audio PLL support"), we are overflowing struct clk_programmable::parent_names on the sama5d2, because there it has 6 parents, while only space for 5 were allocated. Make the parent_names member of variable size to fix this and to avoid such errors in future.

When the bit is cleared, the ethernet reference clock must be fed into the SoC from an external oscillator; when it's set then the ethernet reference clock is generated internally. The correct setting depends on the board, so we must not set the bit unconditionally during probe of the clock driver. Whether or not the clock is enabled can be selected by the board by removing the clock from the FEC in its dts. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
