i2c: mvtwsi: Fix problem with baud rate calculation 2015-03-18T08:48:42+00:00 Stefan Roese sr@denx.de 2015-03-18T08:30:54+00:00 f582a1583b2c7ae91737f3b1a0b850e7f4ef68bb The current implementation for baudrate calculation is incorrect. This part from the formula: "2 ^ (n + 1)" is not equivalent to (1 << n) but to (2 << n)! This patch fixes this and moves this calculation to a function instead of using a macro. This new function is taken from the Linux kernel. This was detected and tested on the Marvell Armada A38x DB-88F6820-GP eval board.
