commit 915da2b794ce4fc98b1acf64d64354f22a5e4931 upstream
The slave-interface documentation [1] states "the bus driver should transmit the first byte" upon I2C_SLAVE_READ_REQUESTED slave event: - 'val': backend returns first byte to be sent The driver currently ignores the 1st byte to send on this event.

Add spinlock protection on IPCC register update to avoid race condition. Without this fix, stm32_ipcc_set_bits and stm32_ipcc_clr_bits can be called in parallel for different channels. This results in register corruptions.

Start streaming was sometimes failing because of pm_runtime_get_sync() non-0 return value. In fact return value was not an error but a positive value (1), indicating that PM was already enabled. Fix this by going to error path only with negative return value.

Then boot loader applies a clock tree that allows to use all IP's at same time and with the maximum of performance.

Normally it should have and that is what I assumed. I just did a quick test and I'm wrong - as you probably noticed since you're pointing it out. Forget the whole thing and I'll send another set (or two).
