Yes, it should be fixed.
From previous beta testers archive.
PhilE should know more details.

What extra (if any?) GPIO interfaces will the Pi 4 have? All of the extra SPI, UART, etc. that was in development last year, or have there been more updates?
I believe there are more UARTS, and a second SPI port. I *think* there is another I2C which does not have the clock stretching bug, but will need to talk to Phil for more details.
In addition to the legacy peripherals we have:
- 4 new PL011 UARTs with decent sized FIFOs
- 4 new I2C controllers with fixed (or differently broken) clock stretching
- 4 copies of the old SPI controller
All neatly laid out as bank0 auxiliaries so you can trade 1 UART for 1 SPI (4 pins each) or 2 I2Cs (2 pins each).
Also, we added dedicated PWM peripherals for audio, so you can use both at the same time.
